Something good will come from this, Cluck. You will be showing your daughter that no man has the right to treat their partner/spouse in such an awful, degrading way as your husband/her father has treated you. Chances are, in a few years time, he'll do his utmost to treat your daughter in the same way. If/when you leave him, you will be telling your daughter that you both deserve better than that. Just be aware that abusive men like your husband often include their children, once they're "at that difficult stage" of growing up, in the abuse... which helps to perpetuate the cycle. My father adored me until I started school - and then he started to throw his weight around around/aimed at me, too. My mother (who is also abusive) left him when I was 3. She took me and DB2, who was then 13, back to her parents and said that she was going to divorce him. They talked her out of it - said how shameful it would be "to the family" if they had a divorcee for a daughter and grandchildren from a broken home. She went back to him, and because I was 3, I had to go back with her. DB2 was given a choice, because of his age, and he chose to stay with our grandparents. DB1, who was almost 18 at this point, lived outside of the home anyway, but once my mother took me back to my father... he came home every weekend/chance he could to make sure that I was okay. An awfully heavy responsibility to be placed on such young shoulders. But I was stuck there. With a physically abusive, violent father and an emotionally abusive, cold mother. Because my maternal grandparents didn't want the shame of a divorced daughter.
Please don't let anyone talk you out of doing what is best for your child and leaving your abusive marriage. Because my mother went back, and showed me that it is acceptable for a man to dominate a woman he's in a relationship with... that abusive behaviour is love... I ended up in an abusive relationship which I am very fortunate to have escaped with my life from. I am in no doubt that if I'd stayed, he would have killed both myself, and my daughter. Please don't allow that to be your daughter's future.
Your friend sounds amazing for having stepped in, without judgement, to help. For whatever reason a woman needs/has to terminate a pregnancy - she still needs real life shoulders to cry on, and to hold her up for a while. Don't be ashamed to confide in your friends, because that's why they're your friends, surely? They're there because they like/love you, and want what is best for you and your child.
Just remember that you are doing the right thing for you. That you have made the right choice for yourself and your daughter's future.
A friend of mine had an affair and ended up pregnant as a result - but she continued the pregnancy and passed the child off as her unsuspecting husband's. He was delighted as he'd been told he was infertile after a bad case of childhood mumps... but we all knew (know) that his adored only child isn't actually his. It made everyone in our friendship group view the friend who lied to her husband and who is now lying not only to him, but also to their child, very differently.
