American repatriating with children

I am not sure whether this falls into Immigration or Family law. I am an American citizen residing in the UK. I have two children by an British citizen to whom I am currently married with no separation agreement or divorce pending or in place. I would like to take my children back to the US to file for divorce as I have no means of physical, financial or emotional support here in the UK. My children have their US citizen born abroad certificates, as well as US passports. Can I just take them to the US permanently? I have consulted lawyers here but they can only advise on UK law for residents. I am totally alone here and while I don't fear my husband, he's a drinker and not always rational. He's very emotional, and I'm afraid if I try to leave him and stay in the country, something unpleasant may happen to us. He is currently applying for his residency to move to the US as well. I don't want to deny him custody, I am a full time mother and want to stay that way.

Any advice would be greatly appreciated. I hope this is clear, its difficult to simplify the situation, but the main question I would like answered is: Can I repatriate without the childrens' father if they are American as well.


Thank you in advance.
