1. Found out she was sleeping with the same guy I was, the guy I had been in love with for years. We sat down and had a long heart to heart talk and both promised to be rid of him. Found out a week later she had gone out of her way to do that to me and they were now dating. And she ended up actually cheating on him.
Honestly though, I'm grateful that it happened. It led to me getting rid of all of my toxic friends and I now have an amazing boyfriend and the most supportive group of friends I've ever had.
2. I got sick of the partying, the drugs and the constant "bros" hanging around the house all day. Once I quit smoking weed I realized it was the only thing we had in common.
3. Every single time it's been because they started dating someone. When people start dating they just get glued together.
It's really awkward when you essentially get dumped by a person, and then they want to start hanging out again 6 months later after they cut things off with their significant other.
4. He had a long history of drinking a lot and being obnoxious. That said, he was a very good friend other than that.
But he had a very rigid view of friendship. He moved abroad, and began complaining that I wasn't contacting him enough. I got married, had a kid, had a full-time job, but he basically wanted me to be acting like we were teenagers.
He ended up moving back to my area after a divorce. His drunken behavior got worse. He got frustrated I wouldn't just drop everything and hang out with him.
Finally I told him I was concerned about his drinking, and he went off on me about how terrible a friend I am. We went back and forth for awhile until he finally said not to talk to him.
