<human>: So I'm single and have been dating-seeing various I'm 25, alot of my friends are married/getting married. I met this one girl who I figured I'd give it a shot with just her. My supposed best friend of 20 years I found out has been texting her trying to hang out with her, telling her I'm very manipulative, I cheat on all the girlfriends I've had, I'm a shitty person, I can't be trusted. Pretty much made me out to be king shitbag. She came to me and we worked it out. He's been in a relationship for almost 6 years, And just got married and sits here and texts my girl how he's bored with his marriage and wants some excitement, and has thrown it out he's thought of cheating. I know my girl wouldn't go for it. Should I be the bigger man and just cut him out of my life or could I pull the ultimate dick move and tell his wife all the things he's done, I'd do it infront of him of course, I'm a fan of stabbing you in the front not the back.

Condense the text into a few key points
<bot>: best friend of 15 or so years backstabbed me hard and was trying to get with the girl I'm seeing. And he's married. How should I take this.
