My guy, did I say it was fine? I said she did everything in her power to make their relationship work. He did nothing, and he still is doing nothing. He didn't even try to fix it. He ran away from it and cheated on her. Yes, she cheated, and she is also no good, but he is far worse. He made her feel not loved, unattractive, and ugly. Those are things that a significant other should never make you feel. Judging by your projecting I am assuming you've been cheated on, but this is not the right way my dude.
Neither of them are good, but he is way worse than she is. I don't know why you're so adamant that she is as bad as he was since she put in a shit ton of effort in their relationship where he legit was an iPad kid grown up and running away from her and lying to her making up excuses to not see her.
The married man had all the power to leave her, he is not blameless either. The only and I mean only good innocent person in this story is his wife who got royally fucked by the other 3.
My rant is over, please do me a favor and do not reply with some dumbass take like they both are equal cause they are not.
