What's the best way to end a friendship?
I'm friends with this dude who's very loud, swears a lot, and talks behind his friend's backs. He also feels like he has to be the center of attention and will try to make everything about him. He's also tried to flirt with women and men I've been in relationships with and sometimes his breath stinks. I've tried working out the problems several times and I've had enough. How do I end the friendship?
