P.U.S.H. Your situation is so sad. I know you feel like you have no way out and you feel alone.
I was in an abusive relationship for 14 years! I met my ex when I was 15 and we later married. I had two children with him. I also felt that I could cope with it all, and would get on with having a family and making the best of my situation. I do not regret having my children at all, they are now 6 and 4 but it was infact them which made me confident enough to kick him out and chnage my life! I didn't want them growing up in an environment like that, and even though it wasn't alwyas bad, when he was aggressive my oldest son would jump infront of me and shout 'Stop being nasty to my mummy'. I knew then that a three year old shouldn't be feeling like that and that I owed it to them to change it.
I have to say that I am now due to marry again in two weeks time.. a kind, loving man who loves me and the boys, and who is definitley the man I should be with. But we always have constant grief from my ex... he poisons the children's minds, he demands things, he is aggressive and nasty to me even now when he collects the children sometimes. You can NEVER escape people like that if you have children with them, and even though we haven't seen him since christmas eve I know he will make our lives a misery again as soon as he possibly can. I HATE letting my children go with him, and now I have restricted the access because they don't want to go and he claims he is taking me to court.
You have to try the best you can to escape this man before you are eternally linked to him through children. Be honest with your family and tell them how he treats you, you'll be surprised how supportive your family can be. Don't keep it secret from people who care about you... I did that, and it just makes you lonely.
I give you this advice from someone who really knows the true reality of what you could be getting into. Please get some help from your family.
