The great news is I got married this past summer! She's beautiful, brilliant, but is emotionally competent. Also a BS, but has done a lot of work on herself to deal with it and worked with her ex to raise a very wonderful daughter. Everything is great and we're doing very well together.
The bad news is, somehow my marriage was some breaking point for my daughter. She has now ceased all communication with me, citing "I'll never forgive you for the things you almost did to me" and "I'm afraid of you!" neither of which make any sense, except that in her mind, I somehow almost committed violence to her mom and to her.
She did reach out once and offered to resume communication, conditional on a series of constraints about what I was allowed to talk about and with whom I was allowed to talk, how often we spoke and constraints on any depth of discussion. I knew it was just a setup for failure, so I responded that I wanted an unconstrained relationship with her. Since then, nothing.
I know my ex has been counseling her on why she should cut off contact. Before my daughter cut things off, she would complain about how her Mom just incessantly railed on me in front of her. My only response was "I'm sorry you had to hear that." A couple months ago, ex sent an email, saying she was sorry about the difficulties between daughter and me. I know her well enough to know this was not heartfelt, but an extra twist of the dagger.
Ex believes that I selfishly focused on my own pain, once I discovered her treachery, rather than seeing it as the "cry for help" that she views her affair as. I abandoned her in her moment of need and she'll never forgive me. Nevermind I gave her an extra chance and she did everything she could to betray me in other ways as well.
So, my life is going really well, except for this smoldering hole in my heart. I hope in the next few years my daughter will grow up enough to see what's really going on, but I'm also prepared for that to never happen.
I cannot express how angry I am at her selfish mother, who so willingly inflicts psychological pain on her own daughter to protect her narcissistic ego. At the same time, I view my disentanglement with her to be an enormous relief. My ex sent a bunch of photographs of me and my now wife, whom I knew socially, from twenty years ago, where we are in a group of people socializing, though not directly with each other. There was no commentary, just a weird implication that somehow I had been involved with this woman back then. I think in my ex's mind, she is the victim and somehow I am the villain in all this.
She's doing everything she can to remain a potent force in my life and I'm strictly NC with her.
