I need some help, my girl has BPD, we have been together 6 years and have 2 kids and she wants to have an open relationship. She deals w33d and wanted more customers and got this guys number and he flirted with her, she told me she has been thinking about it for a year but I was going through some personal issues for a year so she didn’t bring it up, our story is long and has us hurting the other person accidentally mostly. I told her I wasn’t comfortable with this and a week later she told me she wanted to do it and if she didn’t “I may go manic and leave for no reason a year or 2 later and cheat on you” neither of us want that but I feel if I let her do this I won’t get her back. Does anyone have any advice or research or resources or treatment we could look at.
