need advice: my friend's gf is a slut

:word: My ex cheated on me. I dumped her like a sac of shit. There is NO reason to cheat in a relationship. Its harsh but tell him. truth hurts…he will get over it. its better than living with the slutbag. whose to say she wont do it again and have him walk in on them, then kill the guy, and go to jail…all because you didint tell him. It could happen :gotme:.
