First of all I dont know why you would EVER move in with someone after dating them for a few weeks. It's not that surprising that she made the decision to dump you pretty quickly, it seems like this kind of behavior is typical for her. Also I understand that you're upset but saying you're happy this guy got re deployed and you hope he gets shot is pretty immature and you shouldn't even give him the power to make you feel like that. One day you're going to be super grateful that this didn't work out and that you didn't end up wasting too much time on this relationship. You're still young and you still have so many things to experience that will all make this girl irrelevant. It's hard to accept now but from my experiemcr one day you just wake up and you're not hurting anymore. And eventually there will be days where you don't even think about her at all. Sorry to hear that this all happened though. I'm relieved to hear you're hanging in there.
