I'll save you the details, but LTR broke up with me and really screwed me over in the process.

The problem is that I'm "faking it until you make it" when it comes to maintaining frame here. I'm pretending like I'm not bothered by the situation, but in reality I'm torn up about it, and I think about it all day.

This is directly caused by the fact that I'm left in the dark about so many aspects of the whole thing. I'm left wondering why did she do this and that, because she fucked with my head for weeks. And it's not like the answer is as simple as "she was boning another guy", because that wouldn't explain half of it. But in an effort to maintain frame I haven't asked any questions since the breakup.

She knows she screwed me over; this was our last exchange:

Me: wish you the best
Her: you too
Her: I'm sorry

I've been really tempted to respond with something like "yeah me too, let me know if you ever want to talk about things" because I fell like I need some closure, man. But I know that's breaking frame, and I would like to keep the possibility of making her a plate open, but at the same time this is affecting my daily life and only she has the answers I'd like. So I just don't know what to do.
