My question to you is, why did you need to write the initial article? You wrote it in a clickbait way so you could profit off your cheating story. That makes your claim to be “just taking responsibility” seem rather hollow. We don’t need to hear your apology. Tell it to your ex. Move on and become a better person. That’s what most normal people who make mistakes like that do.
People who monetise their bad behaviour, flip the blame so that you don’t take full responsibility, expecting both praise and sympathy for “being so honest” — sorry but I don’t respect you for that. Do I think you’re a slut or an irrevocably bad person? No. But grow up and stop trying to profit off your bad choices while trying to get clout for your “brave confession” and crying sexism when people call you out. Did some commenters go too far? Yes. Does that mean, as your headline suggests, that all negative responses to your article are based in sexism rather than, idk, a revulsion against cheaters in general? No.
