Are you saying you think she might go back to him?
or that she might go to someone who would do the same thing?
How is your relationship with her now?
What are your ages?
It is troubling, knowing that someone you loved was once in this situation, and if they are different now, you wonder, why weren't they different then? The fact is, people change and they learn from their mistakes. There was a reason that she was able to be taken advantage or at that time, maybe it was childhood troubles, or falling for the wrong man. The issue is, when a woman is in a relationship with an abuser, certain things happen that don't happen in a normal relationship. The abuser is adept at controlling people and being manipulative. He would have known what to do to keep her under control with fear and intimidation. There's really no explaining it, its something that if we could come up with the answer or the reasoning, we could probably make a fortune. All that is known is that it's very difficult for the woman to get out from under this type of person. She's very lucky to have done so, I would be very proud of her, and tell her so. Perhaps she does overcompensate, but you should also tell her you are not that other man, and being together so long, she should have enough trust in your where she no longer needs to do that. I welcome your thoughts, let me know if you want to talk more.
