My ex is cheating on his new girlfriend. Should I tell her?
Me , my ex and his ( new ) girlfriend all go to the same school. I found out he’s cheating on his girlfriend with a girl I’m acquainted with , he asked the other girl to be his girlfriend. My acquaintance knows he has a girlfriend , however should I tell his girlfriend, he cheated, or should I stay out of it.

Background-I don’t like my ex he treated me very badly and is very toxic and it’s upsetting to see him manipulate another female.
