Straight up: I do not have bpd. I have bp2, and it is mostly well-managed. I have no idea how hard it is to live with bpd, but I try and understand to the best of my abilities. 

I love my girlfriend deeply, and I know she loves me. When she splits, I worry that I’m not supporting her enough. I know her brain is trying to protect her from hypothetical pain, and I want to help soothe that. Besides reminding her that I love her and I will not leave, what can I do to help her?
