Your friend might not have had his life ruined if he didn’t get drunk and have sex with her and then shunned her the next day. I’m not saying it’s fair but any guy who has intimate relations with a girl and then shuns her when he sobers up is a loser. Are you willing to apply that equally against women who do similar things?
Should a man have the ability to ruin a woman's life if he feels she has humiliated him?
