Very good that you got out of that situation, but now you should focus on your chilern's needs, and getting them counseling if they need it. You don't elaborate on what the abuse was but if you don't get couseling for them it will come out in negative behaviors, or in school. How are the kids since you left? You will always have the memory of being abused but the fact that you did not stay and take it will give you more strenght and you can have your dignity back and feels pretty good, doesn't it. Give yourself that credit and hold your head high! You did it girl, good for you!! With good couseling, I would suggest a psycholgist (ms) not a psychiatrist. That's a really good start to make you family whole again. Good luck.
You got away from him and that was a very brave thing to do, and the best thing for you and your children. I would recommend counseling for both you and your kids.
Could you enlarge on the fact of them being abuse , were you aware of it, what were the circumstances ?
