While she's not the worst compared to the information I've read on BPD, it is clear as day that she suffers from it. I read the stories and thought, "My God, that was my entire marriage." Because I was laid off and we had to file bankruptcy, we moved in with her parents. Things were always rough, but it finally got to the point where I couldn't take it any more, and kicking her out obviously wasn't an option. So I left.
We got divorced, and I accepted joint legal custody and parenting time equal to two weekends a month and a week during summer for vacation, trying to maintain some sense of normalcy for the kids and to make things as easy on them as possible. I moved for a job (within the 100 mile radius per law) and only see them on my days. I would call to talk to them each day, but that means having to talk to her, and the less I talk to her, the better. Right now they are fairly young, 8 and 5. I'm finally getting settled in the area for the new job, and focusing on getting my affairs in order. She still lives with her parents, has no job, and continues to float from one educational program to the next. I'm scared as hell as to what those kids will go through if one of her parents should pass away, not because of the loss of a grandparent, but their mother's reaction to such loss. Physically, she's not abusive, but I know how she treated me both verbally and emotionally during our marriage, and I hate to think about my kids going through that.
I don't know when/how to approach the subject with them. See, when she's not having an episode, she calls me a caring father who would do anything for his kids. But during those occasions? I'm everything but a white-boy. When I think about the future, I picture her telling the kids about emancipation, only to find them deciding to come live with me. But what if she doesn't? I'm afraid if I approach the subject too soon, it will get back to her, and she'll claim I'm trying to take the kids from her, to turn them against me. I don't want to take them from her; I want her to get the help she needs.
