<human>: So I've recently read too many stories in /r/imgoingtohellforthis and apparently the jokes I found mediocre level offensive were REALLY offensive... I am having a vacation in Dubai at the moment and I saw this pretty girl I always wanted to talk to, later I found out she was a model and everything was looking great! I met her on the beach with other models and started a conversation like I usually do, I took her number and we started chatting, she invited me to her room with other Russian girls, I was ready. I knew I shouldn't fuck up this time and everything will be perfect. Well when I entered their hotel room I didn't see vodka... Later I found out two of the girls don't drink so the other two aren't drinking either. That's a bummer, I honestly thought we'd get drunk and fool around, unfortunately it did not happen like i dreamt it to be. So later we've been making jokes, and since I've read too many goingtohell stories I decided to be funny and tell that joke about black people(read in the comments). She then told me that she was engaged with a black person and she found it very offensive. After that incident I just shut my mouth and just nodded in agreement. I never felt so embarrassed and right now I feel bad. I really liked her and turns out she's engaged with a person I made a joke about... FML

Could you distill the essence of the text into 1-3 sentences?
<bot>: Told an offensive joke about black people to the girl I really like, turns out she was engaged with a black guy and I fucked up big time.
