I'm just confused I guess. What was the final straw? You getting jealous because he was sleep talking her or her being to clingy?
Really, the real issue was the clinginess. I think that had she been a healthier partner, the sleep talking would have bothered me less, and he overreacted out of his own guilt. It was like taking the cap off of a pressure valve, and it triggered a lot that was building up.
And no, I do not know of any perfect relationships, poly or otherwise. However when you say your closing the door on something and then reopen it two days later it just makes me think there is some hasty decision making going on. And that fine when it's just the 2 of you but when you start to include other people I think that can start to be a problem.
The decision to close the door was a kneejerk panic reaction, yes. We've talked about that, too; I told him I don't want to do the rollercoaster anymore, and this is a good thing. I think he's figured out that's not really an option anymore; not just for me; I can't change who I am, but... he can't either. This is who he is now.
For the record, he tried to be very kind in breaking up with her; very understanding, with the intent of being friends (as he is with the other women he's dated-- he still talk to his other ex girlfriend.) She just then decided to lose her shit, and we had to kinda cut her off unkindly and abruptly.
I think it was more him thinking he hurt me more than he did, that I would never recover. He didn't want to lose me.
None of it was necessary.
He broke up with her, and then we talked about ending the poly afterwards. We didn't go OH GOD, NO MORE POLY and end it all with everyone we were in contact with. No one else was involved in that, certainly no long-term relationships on the line. (Though I talked to my guy, and he was understanding and accepting, and wanted to know if we could still talk. He's also okay with us keeping it where we are right now; flirting, talking, hanging out.
