Good point, in regards to that her lies did hurt OP (unintentional as that may have been). FWIW I didn’t think OP is a bad person, it was a difficult situation and in the heat of the moment, I can’t claim that I would have necessarily acted differently (hell, I’d say I genuinely used to be a bad, or overly spiteful/vengeful/malicious person about such things).

My comment wasn’t written as, or intended as a judgement of OP’s character (which wouldn’t be defined by just one thing, hell, “good” people can do “bad” things), that said. I just wanted to bring up what everyone else here seemed to have not considered- what I’d like to think I’d do, if I approached things from a calm and collected manner, and the insights that I’ve had shared with me from others (not always taking lies personally definitely wasn’t something I learnt myself).

There’s all sorts of reasons why someone could cheat, or even (highly circumstantial and uncommon) reasons why someone should cheat. And seeing all the comments moralizing about always outing or condemning cheaters also just put a bad taste in my mouth (as someone who’s never cheated, myself- though coming from the childhood I did, I can’t claim possessiveness/exclusivity matters in the slightest to me).
