Long story short: My girlfriend went on a college trip to canada for the weekend, it's just a getaway thing... Her and some of her friends (mostly guys) are at the bars right now (legally drinking at 18+) and it's her first time drinking. I expressed my insecurity to her about this and she got angry... then this happened:
She gets a mobile IM saying I'm kissing a girl (complete lie), she tells me and she's hurt/angry, but told me I don't have to explain myself.
Meanwhile, I asked her to vent, and she blew up at me, nit picking all of my flaws. I asked for it though, so I take it. She storms off angry, then I findout that her friends from a long time ago (who are friends of her exs) have been trying to get her to dump me for awhile. I'm left to trust one of the guys there to watch her and make sure she doesn't do anything stupid (drinking for her first time). Later she calls and resolves some issues to a point that she's calm, doesn't say "I love you too".
Hour later I get IM'd from the same person who lied to her earlier, telling her I kissed a girl. I argue with this person for awhile (they say stuff so twisted it makes me naseous), and everything they say to me, her friends said to her (word for word, verbatim) So I forward the convo to her facebook inbox, and text her telling her what happened and what I believed. She argues with me and then says "What the f*** ever. I don't feel like dealing with this. F*** off"
Then (apparently) her friend jeremy takes the phone and texts me saying "dude she's pissed, you might want to leave her alone or you both may do something you'll regret."
Now I'm sitting here, far far away from my girlfriend and I don't know what to do. She returns tomorrow at 7PM but this whole situation has me feeling horribly sick... (apologies for the length)
