Ok, first post. This has been bothering me a while now and I've been reading the posts here and it's gotten annoying enough for me to post about so here goes...
Basically, short story is: I was dating a girl for a year and a half, the last bit was long distance. I think everything's fine, she comes to visit for two weeks and things are great (she's saying "I love you" and the whole nine yards) and after she leaves I found out she was cheating on me with a guy where she's living for the few weeks before she visited thanks to some evidence she left on my computer. I confront her, break up with her (not much chance of working it out over distance). That was two and a half weeks ago.
I've contacted her a few times since with text messages, kept it civil and nice - she's been very cooperative about sending stuff back, seems to want to keep in touch, I told her I forgave her and all that stuff. This is all no good and hard to handle for me, but I haven't broken down or called her (aside from the night I found out).
What bothers me about this whole thing is that she seemed very upset by the fact that we were breaking up, but now she's with this other guy all the time (I still talk to her roommates). All the time. How can somebody get serious about a relationship two weeks after ending one with someone they claim to love? I expected crying, apologies, something but not this complete indifference. I guess I should have taken it as a warning when we started going out three weeks after her previous boyfriend (3 and a half years).
I don't know if I want her back, maybe I do but I'm not sure. I have no idea what to do, is my ex just plain evil? I don't think I can accept that, but the whole thing is just so heartless.
