I had an affair with a younger man and he's decided that not only can we not be friends, but he's spreading shit about me to our mutual friends. He was my best friend and now he's getting viscious. I don't know why - we didn't fight at the end, just agreed that the friendship wouldn't work. and now my credit is in jeopardy cause I was stupid enough to co-sign a loan for him. I feel like a complete schmuck.
