What type of suit can I bring against "The Other Woman" in 15 yr affair?

I live in Virginia, the other woman lives in Florida, I have been married for 23 years. Found out last year my husband had been having an affair for over 15 yrs with a woman in Florida where he worked for a brief time (caught him in a lie about being on his cell phone late at night and called the number).
The "Other Woman" has been very rude and has stated that their relationship was just between the two of them and had nothing to do with me. But my life and our life has been shared with someone I know nothing about nor gave consent to even being part of my life. She called my home for years and hung up the phone, this didn't happen often but now I know it was her. She moved to our city in Virginia about 12 years ago for about a year and then moved back to Florida when she didn't get the time she wanted from my husband and couldn't pay her bills with the money she was making here. But she did continue to fly to Virginia 2 to 3 times a year for 3 day weekends and she met him when he was on a couple business trips and they talked daily while he was at work and from our home when I wasn't here and from his cell phone where ever he was at.
Last year she filed a stalking suit against me because I drove to Florida so I could meet the person who was such a big part of my life and who knew so much about me. I did not get to see her or talk to her so I drove home without incident. There were never plans for anything ugly, just to talk to this disgusting person who had been so hateful to me over the telephone and see her face and look into her eyes. The case was dismissed by the Judge but I did have to fly there and appear in court.
Over the past several months when I have received a hang up call I have in turn called this woman and hung up after she answers just to let her know that I am sure she is the person calling me. On Monday I received a call from an investigator with the police department making a written report telling me that this "Other Woman" is filing a civil suit agains me for harrasment and causing her stress. I want to know what I can do living here in Virginia against this disgusting person who has taken so much away from my life and is still trying to cuase me pain.
There is no place I can go in my town that I don't have horrible feelings inside because I know that the whole time I have lived here my life has been a lie and she has stayed at four or five hotels with my husband, she has lived here in an apartment, and worked here at a business I have to drive by often. Every time I use the phone or look at something in our home we purchased on one of the weekends she was here with my husband, or watch my husband use the phone or cell phone, and many more normal everyday functions, it kills me inside. I was committed to a hospital last year for several days because I had been put on an antidepresant medication and wasn't sleeping or eating, so the physician asked me to go willingly to get my medication stable and my eating and sleeping stable. Plus I know have been served by my local police department and have had to participate in a very humiliating court where now the records will always be available to the public. I had never had any problems in my life and haven't even had a speeding ticket in over 25 years.
We are working through things and I do want to keep my marriage even though I know that my husband is even more responsible than this woman is for my pain. But it is how she has treated me. What can I do to make this womans life a little miserable since she has participated in taking so much from me for so many years and has caused me so much pain since I found out about her? I don't know who to call nor do I know if there is even anything I can do legally to this person. I sure hope there is since she is so quick and comfortable using the judicial system at the drop of a hat.
Thanks for any help.

The "Other Woman" will get what she has coming to her eventually. Things just tend to work out that way. Why are you not more concerned with the injuries that the man who swore to love and cherish you has brought on? She made no promises to honor you, but he did. This is all a result of his choices. Hang in there. I have my fingers crossed for you.

Thanks for your kind response!
I am very upset about my husband and have been seeing a therapist, and he has also been seeing the therapist as well. There is hardly anything right now that I don't second guess since I was so trusting and believing for 26 years this coming July. But when you have made a mental choice to love someone on a daily basis for all those years and you know deep in your heart that there is something good in that person or you would have never fallen for him in the first place and lived with him that long, you want to try and make your marriage work if at all possible.
Our life has changed so much and he has changed and become the man I knew was there all along. He is very thankful I have not left him and he seems to be very sad and sorry he didn't have the character to walk away from this co-worker before he let anything happen. He told me that he has never bought one thing for her nor have they even been to a restaurant and eaten together. She paid for her hotel rooms, plane tickets, rental cars, and anything else. We did pay for the phone calls prior to the type of calling plan we now have but I never suspected anything so I never looked at the detail phone bill. My whole family lives in different states around the country so I always had a lot of long distant calls and never thought to check behind him on anything. He has been a good husband to me and a good provider. Our intimate life was lacking but it wasn't completely gone and I helped him get medical attention at least 5 times over the past 14 years to see physicians for some depression and to see if anything was going on physicially for him to have a low desire for intimacy. Now I know that he was getting all he wanted and more from this "Other Woman" several times a year and they also spoke regularly. He told me and the therapist that what she offered him was sex and I think he had a sex addiction and what he got from her was non-personal and had no strings attached. He has a very difficult childhood with a father who drank and was verbally abusive and that has carried over into his life so I have always contributed his problems with that reason.
We have a very long way to go and I don't know when I will be able to let my guard down and love the way I did before. But I do believe he is worth fighting for and he is worth trying hard to get rid of some of this pain so we can have a loving and genuine marriage.
On the other hand, this person he chose to have this affair with has been very cruel to me and is still calling him. When I was trying to get answers to some of my questions and I was calling her (she was also calling me) and we were emailing each other, it wasn't very pretty and I am very ashamed at how I allowed the pain to drive my actions with her, but she was so rude and ugly to me. She wound up filing charges against me for stalking, they were dropped but we had to go to court and that was the first time I have ever had any type of problems and been to court. How sad that this is now a part of my life forever and she is now a part of my life forever. I didn't ask for her to be in my life nor am I happy that she knows about me and my family. The whole thing makes me very ill inside.
I have been tested for every type of STD there is including AIDS and I made sure he went and got tested as well. So far all is good. That was a big relief.

I will be 50 this year and feel like the years of our lives that have been wasted were the years our health and activity level were at it's peak. So I can only hope to have many years ahead us that can be spent without wasting another moment.

Thanks again and I am sorry to have chatted so much.

I don't know whether or not you are still viewing this thread, but I came across across your post and I am in a similar situation. I think you and I have similar values. My husband, we have only been married for almost 5 years but have two kids and one on the way. He left us without any warning and his phone message was that he was leaving and filing for divorce. This was earlier int he year. Now, I moved out of that town and I am staying with family here. My 3.5 year old son has a speech delay. At the time, I suspected autism but I have worked with him for over 1.5 years to get any mercury toxicity from his system and with speech therapy as well. He made a lot of progress but guess what happenned? We moved into a new house in a new neighbourhood and my husband chose this time to leave us. My son would look out the window on so many days asking for daddy. He became withdrawn and very sad. Children no matter how young can get affected by all this. This other woman ( I didn't know there was one at the time) had apparently said the children are little they won't remember anything. All i know is that my son regressed and it was painful for me. I do blame my husband for being a ****, but I know that he has always been the sort of person who was easily influenced by others. This woman wrote so many emails to him (this is how I found out about the affair) directing every course of his life. She gave him pointers to tell the divorce lawyer, she hinted at him suing for custody of the kids, she also hinted that he should bring someone with him to see the kids in case I had a breakdown. How cruel can somebody get? My husband said that I was so busy with the children that I was very distant with him. That's not true at all. I remember in great deal pretty much all our life events and I even confronted him many times in the last year with great concern about our lack of intimacy. I only called the other woman once from my husband's cell phone because I saw all his messages. She went to her boss at work and complained about a harassing phone call and my husband claimed he was called in to give an explanation - I don't believe any of it. I was thinking, since they work together, I would get a lawyer to send a letter to her superiors (after he leaves the workplace permanently) perhaps with some sort of violation of their ethics. hope she will be reprimanded. I don't know what will happen to my marriage, it has been like a rolller coaster which is why the kids and I went to stay with relatives until he gets out of that town. I just didn't want any additional stress on my kids or on my pregnancy and my husband is so unstable. Ever since I found out about the other woman, he has been secretive, has passwords on everything. I trust that God will somehow give this woman some kind of reprimand, but where my children are concerned, she has no business looking up child care centers or to convince my husband to build a "case" around my emotional state. I had it pretty darn together despite what she tried to do to me. The best, best, thing I did was to get out of that place. The third pregnancy was not planned, but I look at it as a blessing, even if the marriage ends in divorce. It is hard but now I really blame my husband for the turmoil he brought into our lives. I don't know if she is still in the picture but my gut tells me she is. I am getting used to the idea of a divorce, it's better than being with a man who is easily angered and puts me down whenever he feels like it. I just think that he's changed so much that it is really hard to bring back the innocence of the early years. That's all gone. Now, I have to tiptoe around him and why should I bother? He doesn't really love me or the kids for that matter. If he did, he wouldn't put his personal needs in front of being a proper father. I hope that we all get through this somehow.
