How do I get out of this hell marriage?

We got married last august in LA, she is american and I am northern european and we live in the UK.my life has been a living hell for the last couple of 6 months and things are not getting better. We are expecting a child together bu I can't take it anymore, I have lost all my friends, I can't do anything but report to her and get her approval. I have become completely isolated from a normal life and I cannot even join my local gym or meet my work colleagues after work because she doesn't like gyms or driving. I want out and I don't want anything but my clothes and to see my child. I have nothing for her to take, she has all the money and the house, I have told her that I cannot live like this and that I want a divorce, she now has taken my debit/credit cards, passport and drivers license so that I cannot go anywhere.and she threatens to change locks on the doors if I leave the house. She is a complete nutcase and I just want to get the hell out of this marriage and move on with my life. What can I possibly do to get my belongings back and terminate this marriage? I can't even rent a hotel room without identification.

They you must challenge. if necessary, tear the house apart to look for your ID and whatnot.

If she changes the locks, bust out a window. Get the police involced in this mess

File for a divorce, and worry about the aftermath later. If you walk out on her, where will her income come from? She cant deny you your child, so by law you have the right to be in your childs life. Leave and let her realize what she is doing to you, and she will because its just like they say, "you never know what you have until its gone".

file for divorce and joint custody. tell the court what belongings she has of yours. she legally cannot take your credit and debit cards and identification. they will physically take them from her and give them back to you. if she refuses, she goes to jail. sorry for your strife, she does sound insane.

I'd prefer to hear her side of the story as well. But, if you just want 'out' w/o trying to work it out (you've not said you have gone to marriage counselling), even though you have a child on the way, well then, go to the police station and ask for assistance.
