Pete, that's a great point - that the logical conclusion of the 'what ifs' is that the relationship would have ended sooner. It makes me want to reframe my question from 'what if I did X to save the relationship, to 'what if I had responded as I should have?'
The first time BPDx and I had a fight, we had been together less than 2 months. I'd gone to visit him in his city and it had gone badly. I stated that I felt angry and unsupported because they hadn't done some tasks they'd promised to do to help me, before I came (a 13 hour train ride). I also emphasized that my feelings were not necessarily the whole story, and that I knew he also tried hard to support me in other ways.
BPDx responded by lashing out at me, then spending the next many hours crying and successively messaging/ calling everyone he knew (friends, family) to say that he was a bad person. With the result that many of them called back in concern, which he related to me as if it were my fault. Among the people he called was the affair partner with whom he had destroyed his previous live in relationship. He didn't disclose this to me at the time, he described to me as 'my friend'. He played me off against her, emphasising how she was 'there for' him during this terrible experience.
He also said he couldn't imagine how he could ever trust or feel the same for me again. Bear in mind that I had previously spent a full month just before keeping him under near 24 hour watch, because of his mental health. He had been effusive about how in love he was, how I had 'healed him' etc, yet one conflict or critical remark was enough to completely derail this.
I ended up apologising and struggling to 'fix things', resulting in re-idealisation.
If I had acted as I should have, I would have at minimum demanded that he seek and enter formal mental health treatment at this point. And also not continued the relationship without full acknowledgement of how unstable his actions were, and commitment to change.
It's weird because at the time, I very quickly realised he met the criteria for BPD, and that his actions were kind of, well, crazy. And yet I didn't insist on the above because... well... I don't know. I wanted to believe he was a reasonable person, that the fairytale partnership I had been offered was still viable. Those were my delusions, not his.
Under The Bridge, it's funny you use the 'failed them' phrase because that's exactly what BPDx said to me during one of his last 3.5 hour spirals. Hours later, he was happy and 'fine' again and seemed to want to act like it had never happened. The double standard between what I was supposed to just absorb, and his propensity to meltdown from much less, is stunning.
