Hey loonsong,
Hopefully he will feel better. As you are a new poster suffering from BPD, I want to warn, what you read in this sub-forum is probably going to trigger you, so be forewarned.
Way back when this sub-forum was created, the original creator wrote it so well here -
family-support/topic120765.html#p1285735
"This thread, as I said before, is intended to help the friends and relatives of those with a disorder to keep THEMSELVES emotionally healthy and safe, because they are constantly in a position of giving help and support, often at the expense of themselves."As you wrote, there really is no one person's fault, but ... this sub-forum is first and foremost meant to support the friends, relatives, and romantic partners of those with a disorder, just as written above, because they often already have been above and beyond (near constantly) supportive, and need some support for themselves.
I suspect the OP is a good guy, and has supported her. I also suspect that if they do break up, once he is gone through the grieving process, he will reach a point of compassion at a distance for her disorder. Most here eventually do. But the thing is, the significant others here really do hurt too. Many describe their experience as the most painful of their lives, and that's because it really is.
So from the point of view of this sub-forum, we try to avoid censorship, judgement, if someone needs to be angry, critical, question, yep, even temporarily hate their PD partner, it's fine. Emotions pass, but avoiding them can leave someone feeling permanently unwell.
Anyway, you and others with BPD are welcome to read here, but yep, the scales here are tripped toward what the significant others need. Similarly, we discourage the SOs from posting in the BPD, HPD, NPD, etc. forums if they are triggered.
Best,
xdude
