Just finished working late and there's nobody up to talk to, feeling crappy so thought I'd update this thread.
We talked a lot more and she's agreed to move out. She's got so many issues, which I've known about for a long time, that I'm no longer angry at her. Just sad.
I know for 100% fact she didn't sleep with the guy. Believe it or not, I know it for reasons too complicated to explain. Doesn't change the betrayal.
We ended up sleeping together on Sat night. Dumb move, yeah, whatever. It's hard to do the smart thing in this situation.
So we're separating. If she can stand on her own two feet, grow up and become a woman, and if we still want each other by then, I'm actually open to trying again. It will talk a lot of proving on her part. But I'm not filing for divorce just yet.
Typing that out and then thinking of what she did, I feel stupid for saying it. A lot's gonna change over the next few months though, to the point where how I feel about her now probably doesn't matter much.
Just gonna work hard and have some fun on my own now.
Thanks again GAF for all the support and good advice
