Thanks for the kind words pbetra,
It helps to know all that I wrote about. I knew going into our R that my W had major family issues re: her father. But I thought that she had learned from her experiences, she said she did. And with the fact that he wasn't a big part of her life (he didn't even bother to tell her when he remarried, let alone be invited to the wedding), I thought I was "safe" from his negative influence. All it took was him coming back in her life at a "bad" time when she was already going through a transition, and that was it. The little 10 year old girl inside her who so wanted (wants) her daddy's love came out to play.

The problem now is there is nothing I can do. There is no way for me to help pull her back to reality. Her father has now destroyed not only his family but my and his D's family as well. What makes someone so very evil as to even WANT to do that? How does a grown man act the way he does and have zero remorse?

I have always tried my best to be the best father I can be to my girls. I know one day they will leave and start families of their own and while I'll still be a part of their lives, I understand that is their time to live the best life possible. To have the ups and downs, good and bad of their own family. I KNOW that they will never be hurt by the things I do now. If only their mother were strong enough to break free of the awful past her father gave her.
