Not sure where I implied it was habitual, but I do agree that there are men who are habitual cheaters, just like their are women who cheat habitually (ask anyone in military service with a wife back home). Unless you were talking about the dude who comes into money and gets a ho bag 20 something mistress, but that due is a special kind of scumbag. Even then, that scenario is far less frequent than a woman who is psycho and makes her husband jump through emotional hoops for the most basic shit on a daily basis. Even then, the typical male cheater is generally not ending his real relationship, he is just being a complete disrespectful asshole. The whole process women go through when they make sure their hand is wrapped around the next dick before letting go of the last one, then mentally justifying emotionally bulldozing the previous dude when she does bail, is a lot more sadistic than "My wife is not putting out and I am tapping this shit on the side". But neither are morally acceptable, obviously.
Also, what you are describing as being a recoverable cheating scenario is physical cheating, which is what most male cheaters engage in. Unless they are trying to dump the crazy, no man goes out looking for a woman to start a relationship with. And certainly no average man is going to ditch out on a long term relationship that he feels is going well to try and upgrade to a slightly better one. Women do that shit ALL the fucking time, then they rationalize it in their minds and punish the fuck out of the previous guy to feel justified. Plus they brainwash you into thinking it was your fucking fault.
Look at Onoes's situation. Wife basically stopped putting out and was lining up her next dick behind his back. They agree to separate, but he is still buying HER shit for her new house and she has the balls to bitch when he won't buy some extra bullshit for her. And the dude thinks it was amicable and that he is not going to get royally fucked down the road.... sure maybe. But its a lot more likely she is already balling meal ticket number two and waiting for the papers to go through (not that it would change anything, but she probably feels better about herself waiting to get it out in the open) and she had made the plan to switch to a new dude a long time ago. In fact, I am willing to wager that the guy Onoes caught her sexting with over a year ago is going to end up moving in and raw dogging her on the new bed he was nice enough to buy her sometime later this year. Meanwhile, poor Onoes is so starved for pussy that he almost got locked down to the first crazy facebook hookup that got tossed in his lap. I would also further wager (based on a friend's past situation) that she nailed her pussy shut as a gambit to get him to cheat so she could feel justified in dumping him, but he was too loyal to stray before her careless behavior led her to being caught in the act, but that's just speculation. And this is a relatively friendly and benign female initiated separation.
