Cheating on a partner should never be considered valid. By cheating, I mean infidelity over a stable partner. There are many reasons for this and I'll try to be succint. Also keep in mind English isn't my main language, so please excuse typos and mistakes.

Cheating hurts your career. This alone makes cheating a no-go for women. Anything that jeopardizes our self reliance and financial stability/independence from males should be avoided as it hurts our own chances at life. Most enterprises/firms will never even consider promotions for people who are known to cheat on their spouses. Think along the lines: Would you trust someone who cheats the one they sleep with? I know I won't, and so do you.

It also hurts your reputation, and this brings way more problem than any benefit of a revenge on a piece of shit partner.

Cheating may put you in danger of physical violence. Most men can become really angry after being cheated on, even if they cheated first. Especially if they cheated first. Society have been carefully engineered by males in positions of power to treat male cheaters with more lenience (the whole "seed spreader" phylosophy) than female cheates (the "homewrecker" thing), and therefore there are countries to this day that executes females who supposedly cheat but do nothing against males who ostensibly do.

Cheating culture actually benefits males. So, taking part in this to hurt a male actually ends up benefitting a lot more males who end up getting laid without little to no effort. People who cheat often bring down parameters since their objetive isn't an emotional bond or a serious relationship. This culture benefits most of the low value male side in the dating scenario.

Cheating contradicts the free state of women. To cheat one has to disdain someone they liked to the point of entering a relationship with them. However if we disdain a male we are in a relationship we won't (or at least shouldn't) have any problem dumping his ass. We don't really need a motive. Any male who's considered to be cheated on should already be packing on their way. Cheating, by definition, contradicts the state of a free woman, which would dump any male years before any serious motivation for cheating.

Please let me know what you think of this.
