Me and said flatmate used to be really good friends, but we both liked this girl that's living with us. I have to admit there isn't much chemistry between us though, it was mostly peripheral. Anyway my flatmate can keep talking shite forever and he often stays up late to talk to her (or at her, she's quiet). We were out one night though (not my flatmate, he's only 17 and cant go clubbing), and the girl pulled (made out with) multiple random guys, I was pretty drunk and on the way home I called her a slag.
For some reason when my flatmate found out that I called her a slag he started acting really cold around me and told me that he didn't like me even though we got on really well before and had a tight friendship. When I apologised to the girl, she told my flatmate to be friends with me again and at her word, he instantly forgave me and started acting normally.
What is that all about?? I personally think he was just trying to get in good with the girl, and if he could toss me aside like that should I even be friends with him again?
