<human>: Tonight, I went out to a club with some friends and ended up making out with this girl. Not a problem usually, but I've been in a monogamous relationship for a year and a half and this girl was not my girlfriend. I was really drunk and this girl basically threw herself at me but I feel SO guilty and I feel like the biggest asshole in the history of the world. Here's the real problem. I'm head over heels and supremely in love with my girlfriend. She's the only person who truly gets me and if I broke up with her, I'd be completely lost. I don't know why I did what I did, but I know that I cannot leave my girlfriend. I just need people's opinions on this. I want to hear as much as possible just so I can try and push this voice out of my head telling me that I am the worst kind of person. I love my girlfriend. She has helped me grow through really tough times and I don't want to lose her. I know her and if I told her what happened she would freak the fuck out and it would probably be the end of us. I literally cannot have that. I don't want to hear what I *should* do or what an asshole I am. I just want to hear people opinions on this matter. I need to hear a voice other than my own. Sorry I'm kind of upset right now.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Made out with a girl other than my GF, can't tell my GF because I love her more than anything. Just talk to me.
