Search Results: why did he ask me to stay at his place

I went to her city 2 weeks ago and we went out and had fan. At some point we met with her boyfriend and his friends. I was making eye contact with one of them and ended up kissing with him at the end of the night. I was drunk enough to say stupid things but not drunk enough to DO stupid things. Then his other friends left and it was only me, my friend, her boyfriend and the dude I was making out. Through the entire night my friend tried to split us claiming that I was drunk and he was taking advantage of me. The guy though was very kind and nice. He even suggested I stay one more night so we could meet when I was completely sober but I couldn't. When we started going to her place me and this guy left them (without them knowing it) to go to his place. Dick move, I admit I shouldn't have left like this. Anyway the next morning I go to her place and I find her extremely mad. Her "reasons" was that I got drunk and that she and her boyfriend had to babysit me through the night so I wouldn't fuck with the first guy I met. Then she asked me to leave and we haven't spoken since.
At first I was really sad and upset about it cause I considered her as my second - third best friend. Later I realized that she didn't really have a reason to treat me like this and now I'm mostly mad. I mean, if she thought I was very drunk and was worried about me why didn't she call me when I left, or why wasn't she paying enough attention so I was able to leave?
Can you find any reason in the story to basically end a three year long, good friendship?
