Can you guys tell me about the worst relationship you've been in?

1st major relationship i was in - i was naive & had little confidence & the guy initially came off as nice but totally took advantage. I consented to sex that wasn't the issue but he was very controlling, manipulative, rude to my friends & family, although normal sex was consensual he did pressure me in to anal sex & every time i said no he wud call me selfish, a bitch that sort of thing & once he 'accidentally' shoved his dick into my ass! when i kicked off about it he said it was my fault - actually most things were my fault - if i felt sad or upset about something he was so manipulative i ended up apologizing to him - total ass
