I need some serious advice. I've been talking to this guy for about six months now and everything seemed great we were really close he seems to be the phenomenal person I was really into him but I recently found out that he's married so I had to walk away from him. Do I need to tell his wife that he's a cheater? Because I found out that I know her through people I know so I'm not really like that acquainted with her but I've seen her not knowing that it was his wife. So do I tell her cuz I feel bad and she thinks they're so in love and in this perfect relationship and she has no idea that he's a cheater.
