Her boyfriend and I have similar things about us, but for the most part he's very different. The similarities are in our demeanor / supportive sides. I do agree with you that my D's will not be like their mother.
I don't know if STBXW's future is looking 'good' or 'bad'. I think she is content with the way it is and doesn't really care too much about what happens to me. I know she cares a lot for the girls, but not enough to look at what she's done as being 'bad' for them.
She is sure that her life is 'better' now. I've been stuck in this cycle / slump until the past couple days where I've really been able to internalize that we will get divorced and that I deserve better than what I've gotten. I'm sure she also thinks she deserves better than what I've been able to give her, but she has no idea what I sacrificed of my own self.
Anyway, it's a new year and I'm going to make the best of it.
