Sarah,
I'm so sorry that you have to go through this. I have issues with my mother, but she's a lot more passive-aggressive about it, and seems to be satisfied with a "don't ask, don't tell" approach, which works for me, since I'm thousands of miles away. And I don't have the complications of children, so it must feel like there's no where to go.
I do think it's worth exploring some of those past experiences to see if you are influenced against men, and that vision of men as villains leaves you with a smaller set of choices than you could have. I had to sort through the whole "men as villains" scenario before I saw clearly enough that it wasn't just fear of being a bad man that I was facing, but rather that I wasn't a man at all. Not that I had to face any of the kinds or abuse that you did, you're amazing just to have survived!
You don't mention your own beliefs about God, but if you talk to people, you find that everyone has a different perception and belief, and every one is as valid as another. Maybe she's right in the sense that you can find your identity through God, but that doesn't mean the outcome will meet her expectations. On the odd occasions when I do pray, I pray for the strength to do what I need to do, and the wisdom to see exactly what that is. After that, faith is trusting that you'll get an outcome that's best for you.
I wouldn't let others speak for God, for God may give you the strength and wisdom to pursue the path that brings you peace.
Erin
