Sure, but this is somewhat tautological, and you're not actually refuting anything. You're saying that X (an expectation of monogamy) and Y (adultery) together imply Z (a breakup), and that if X is not true then Z is not necessarily imminent. Well, like, duh? Y implies X in the first place. It wouldn't be adultery if the relationship was not monogamous.
Sounds like you tried cheating and got caught, and now you're mad you're down 2 sets of buttock. Sucks to be you.
