<human>: Can you condense the text into a few key points?

Last night, my girlfriend went out with her friends and she was pretty faded. After she got home she told me (21M) what happened: she tried coke with her guy friends and they started to get really touchy-feely. Later, that one frat guy french kissed her. Side note: She met that guy for the first time, one of her guy friends tried to set my gf up with him two weeks ago though.

Although she told me what happened, I'm really upset and I don't know how I should feel about all that. We have been together for 6 months (long distance relationship) now and I really love her, but this whole thing really shocked me and I feel kinda deceived.

She told me that there wasn't more and that it's not a "big deal" but I'm so f***ing upset. She told me she doesn't like that guy and it doesn't mean anything and she loves me. She also apologized but it's just not off the table for me tbh. I would never have thought that something like that might ever happen. I don't think she cheats on me, but I can't fully trust her either since she made out with a guy on coke. I really don't know what I should do know. I'm deeply hurt and I just can't calm down.
