A pregnant-single-mom-to-be needs a little advice please

I am currently pregnant and I live in California. The father of my unborn child lives in Utah, where I used to visit him when we were together (I have never been a resident of Utah). He also visited me in California (I happened to get pregnant while in Utah). We have never been married. After a 6 year relationship with each other, I got pregnant he decided to start seeing other people and decided he could no longer be "physically committed to me". I stopped visiting Utah for obvious reasons.

I've never denied him the opportunity to be a part of the pregnancy, although he's been absent for the most part. He drops by for the weekend every 2 months or so, so I've seen him about 4-5 times during my pregnancy. He helps me with health insurance and makes sure I have enough money to pay for prenatal bills, which I appreciate. He does want to be a part of our son's life, but I refuse to move to Utah, my life and support from family and friends is here in California. My own family have been the ones helping me physically (Doctors appointments, baby care classes, emotional support, etc. I have a high risk pregnancy.)

Unfortunatley, the father of my child and I are currently unable to work out our relationship. I have never threatened custody issues with him, but he has. He has promised to do everything he can to attack me legally.

I want the best for my son, meaning I am not trying to deny him his father, although his father is not being very nice to me.

He has made a few threats my way:

1. He is going to make me move to Utah by "proving" I lived there before (which is NOT true).

2. He is going to take the baby away from me or get more custody than me so I am the one who has "visitation".

3. He is going to be sure the child has his last name, which I disagree with, since I've been the one who's been physically responsible for this baby during the pregnancy and we are not married.

4. He has more money than I do so he is going to try to prove I am not financially capable of taking care of the baby the way he is.

Do any of these threats hold water?

What would be a likely/fair custody arrangement outcome be like since we live in seperate states?

Any advice on how to handle this situation?

PS (just in case you need to ask)- I am NOT a drug user or abuser, I am not a crack***** or prostitute. I do have a pretty good head on my shoulders other than having not so great judgement in this last boyfriend. I am well over 18.

Thank you for taking the time to read my post!
