Sounds like she is still being abused by this man- at least emotionally. But if she doesn't acknowledge that there is a problem, and if she doesn't want your help. There is nothing you can go about it. I would just say, "Look I am here if you need me." But just leave her alone for a while. I would check on her maybe once a week, and I know it's easier said than done...but she will only push you away if you get too close and she's not ready for you. The only reason I say this is cuz I was in a bad relationship with my ex...and I wanted to get away...to start up a new relationship with another man...but I always went back to my ex. He just had that much mental control over me. So, I am thinking...she is glad to have you around...but she still loves her ex especially since it's her child's father. There is also the factor, that she may be using you. She may need comfort...and she chooses you when the ex is not around...don't get mad. It's just my opinion. Take it or leave it. You don't have to listen to me.
