Thanks for book suggestion L&L. I have purchased it and will try to get stuck into it this weekend. I feel a little better than I did but am still angry that he thinks its OK to have his girlfriend in and out of his daughters life. From October I will need his cooperation so I can go back to shift work but his cooperation seems to be dependent on whether his girlfriend is available to babysit.
I would feel angry too. My ex is practically a hermit, so I haven't had to deal with this. I would imagine it might be easier in some ways if he could hold onto
one girlfriend, because then you have a somewhat stationary object you can study and get to understand better. Sometimes you read stories on this board where the SO of the exBPD is actually an ally, because that person is making sure nothing too nutty happens around your child.
Also, if you have a therapist, I would ask about what to say to your D. I learned the hard way that not talking about stuff can really mess up your kid. But my son was 13 when I got real with him, and by then I had worked through a lot of my anger and grief, so I could focus on him. It was still hard, the conversation kept coming back to me, but I worked at it over a period of a couple weeks with my therapist and S13 developed a really solid relationship. If you navigate this stuff carefully, amazing things can grow in your kids. My son is wise beyond his years. He still has issues, and I definitely messed up a lot, but we have a pretty strong bond.
I feel like I'm steering him into emotional healthiness, and that's paying off big time for both of us.
Keep posting and let people know how you're doing. I learned so much from people here, and felt a lot better getting out my frustrations to people who really understand.
