We're sorry to hear of the painful situation you're in, but are glad you've found us. Here you can learn to better understand BPD and some coping skills that will help you to be more effective in your relationship. One of the hardest things to accept is that we cannot control the actions of our pwBPD, even if they are harmful to us. This page on
setting boundaries talks about how to protect ourselves even given that reality.
Don't reach out to her therapist directly. That risks breaking the bond between her and the therapist, and you want her to be seeing a therapist. Look to couples therapy. You can sign a release so that your therapist can talk to the couples therapist, and she can do the same with her therapist. You could suggest this in couples therapy.
I'd advise against contacting the other guy. He must know she's married, so you can't appeal to his sense of morality. It also risks conflict between him and you which can lead to all sorts of trouble. Don't make any ultimatums to her either, unless you're willing to follow through. Best to work with the therapists and skill build here for a bit.
What are the most common sources of friction between the two of you day-to-day?
