If he's ruining your game by AMOGing you, sure discredit him. AMOG him back. If he isn't effecting your game, buddy up to him. An alphas friend has a good chance with the ones he's not into.
Your interest in other peoples relationships I don't understand though. Unless you are transferring your relationship issues onto the husbands with cheating wives. That's a separate issue all together. The answer to that isn't ruining his life but getting in better control of yours. These women didn't cheat on you. If you are worried about a girlfriend cheating on you when you bring her around that is something you will have to deal with whether you expose him or not.
