Ok this isn't so much an AIBU because I know I have been. 100% I know I have been a complete dick.
I slept with a friend tonight, he has a long term serious girlfriend. I have to be in his company tomorrow night. I do not know what to do.
I am fully aware what a horrible person I am right now. There is absolutely no way I can get out of tomorrow. I have zero intention of it happening again although he has different ideas which I have tried to put firmly out of his head.
It was a mistake but life will dictate that I have to spend time with this man in future.
I made a mistake and I am sorry but need a bit of advice on how to move forward...
