<human>: Could you distill the essence of the text into 1-3 sentences?

Time to get it off your chest, you scumbag.

My biggest scumbag moment would have to be when I first came to college.

Little bit of backstory: I was always pretty unpopular, but towards the end of school the popular kids took me under their wing and stopped people bullying me, always hung out with me and invited me to parties. However I was still definitely not 'cool' by anyone's standards and while I'd barely kissed a girl they all had girlfriends and STILL got laid every week.

Then college rolled around, they kind of grew up and realised cheating wasn't cool, and got on with their lives. I went to a different college really far away, reinvented myself, got a girlfriend and was all happy with myself. Then one drunk night a friend of mine kind of threw herself at me, I still had massive hang-ups from school and thought this was finally my chance. We were just about to get down to it, then she says what about my girlfriend, I tell her not to worry about it.

I thought this would be a one time thing, but nope, fast forward a couple months down the line and I'm basically juggling two relationships and I don't want to be in either but I'm too much of a pussy to end either one. Eventually the second girl says she'll tell my girlfriend if I don't dump her. I awkwardly dump my girlfriend but I'm now too scared to dump the psycho girl because I still don't want my first girlfriend to know I'd cheated on her.

Couple more months down the line and I'm still a gigantic pussy and trapped in a relationship I don't want to be in, all the while cheating on the crazy girl.
<bot>: Cheated on girlfriend, accidentally became polygamous for a while, was forced to dump first girlfriend, kept in sham relationship for ages by crazy girl, all the while cheating on the crazy girl.
