Yes, she seems to be fine with accepting ugly truths.
She told me that her last GF brought up the idea of being in a threesome, which she immediately hated but then cautiously accepted and then found that she couldn't stand it and saw it as cheating and left her because of that. She was amazingly hurt and pissed off at her ex-GF for a while, but they had been together for a couple years and the woman was probably either an LSI or an IEE, I couldn't tell which from a picture, so she was heading into the wind in that relationship anyway.
I'm not sure what her thought process was in reviewing that relationship, but I think it was mostly "the other person did wrong", rather than "we just weren't meant for each other, but we'd be great with other people".
