I once caught my ex girlfriend and her lover in the act. What I did was order the slut to leave the bedroom ( she foolishly gave me a key to her apartment), before deciding to taunt the guy who was with her with insults about him being a coward by keeping their tryst a secret from me, tricking him into attacking me first so I can justify my smack down of him as self defense. At one point I even rammed my thumbs into his eyes, before grabbing him by the collar and throwing him down the stairs and out of the house. Then when my ex asked me what it would take for me to forgive her, I lied that I wouldn’t leave her if she gave me a blowjob followed by anal sex. She did, and I told her it was great and that I was breaking up with her anyway, before leaving her place. Later that night, I stopped by at her older sister’s place and asked her to pretend to be my new girlfriend after telling the woman about her sibling’s treachery, and she consented. I still laugh every time I think about the cheating ex girlfriend’s face when she saw a photo of me and her sister together. Now we are actually together for real.
If you are in a marriage and your wife has cheated, I suggest not filing for divorce as that can be very costly, and instead behaving in a way that would make your wife unable to tolerate you and willing to leave so that she doesn’t have to put up with your mess. A good friend of mine had that problem and he resolved to go home and sit on the couch naked and drinking, not bothering to clean anything up and throwing rubbish around everywhere, basically giving his cheating wife hell. Within two weeks, the adulterous woman had left and he hadn’t had to pay a dime.
