AITA for wanting to make the current girl be aware that my ex is a cheater?
I(20F) broke up with ex(20M) a month ago because he cheated on me. I caught him cheating in March during the time that I was going through a depressive episode of my life, but we still tried to fix our relationship for a month before officially breaking up. During that month that we were still trying to fix the relationship, I caught him again talking to another girl (a different one than from the first time I caught him).
I don’t know if the girl was aware that I was still in the picture while she was talking with my ex, but it looks like she wasn’t based on what I have seen. I am thinking of messaging the girl to make her aware that their relationship came from cheating since I don’t think anybody would want that to happen to them. It also looked like the girl came from a messy relationship before, so I wanted her to also be aware. AITA?
