The only thing we all agree on in this situation is that we're happy they're happy. Hers feel the same way as I understand it. While I'm happy they're happy, I'm not comfortable. And you made a good point in asking if either of us are stable. The truth is, I know I'm not. My flashbacks and dissociation are out of control. And I don't think she's stable either. Neither system sleeps a lot because the other one is usually having nightmares. We aren't okay, neither of us and haven't been for some time. We've always maintained our friendship through it all and I don't want to lose that. I don't think I can handle losing that.
Edit: I do have an alter who is very against it. He doesn't trust anyone (even friends), let alone in a romantic relationship.
