Hey guys! I just stumbled upon a post in "Am I The Jerk?" subreddit. I won't be linking it here because the rules of r/MensRights don't allow to post links to posts in other subreddits but essentially what happened is the OP there (an 18-year-old guy) went to a party at his friends, met a girl he'd talk to earlier, but wasn't interested in because of his loyalty to his girlfriend. He grabbed some drink, left it in the kitchen while going to the toilet. This girl (the bad guy of this story) spoiled it, while OP was absent. Since OP was drunk and couldn't drive home he decided to stay at his friends place. I'll copy/paste what happens next:

"after i drank the drink that i had left out, i came to feel quite numb and it became difficult for me to move around and i started to slur my speech which was weird because i didn’t drink that much. later on in the night i ended up getting helped into my tent in his backyard which i had put up earlier. as i was struggling to sleep i vaguely heard my tent door opening and the girl i used to talk to come into my tent and did certain things i wont mention on here, and i was unable to resist as id been drugged my girlfriend is now mad at me for letting it happen and thinks im dirty, does this make me the jerk or am i overthinking it?"

Some comments suggest that the OP should file a police report and dump that girlfriend. Personally, I think he'll be more successful doing the second thing then the first
