Why do people tolerate the awful things their lovers or spouses do? I am a firm believer in not forgiving cheating. People will do what you allow them to do and treat you how you let them treat you. Think of all the text game posts around the manosphere. A woman could choose to not respond to jerks but she still does. Same goes for guys who forgive cheating. Anyone ever ask why these guys do it? It is not simply beta, omega, loser, or dorkus. It comes down to self esteem and self evaluation. It comes down to how a man (or woman) views their position on the ladder.
The Ladder Theory is that in the dating market, we all stand on a ladder. The rungs are our partners or potential partners. We are reluctant to take steps down from our perceived current spot. We will always look to take steps up. Sometimes we reach for a higher rung well above our spot because of its lofty location. Sometimes people are holding onto a rung that they feel is as high as they will go and their feet are dangling. Note that this spot is usually where a guy will propose to lock a woman down. There is a ladder for both genders, and if you envision the ladder and say a drop in someone's sexual market value, a woman trying to get engaged and latch onto some man at 30 is like a desperate grab to hold onto their spot on the ladder.
When you read these horror stories of women (let me focus on the bad woman, forgiving man scenario) behaving badly and guys taking them back, look at the guy. He is probably reaching high above where he really places himself on the ladder. If not, he might be valuing himself really low. The message I send of never forgiving cheating is that woman is bound to do it again. Even if you think she is hot, there is always someone younger and who has not betrayed your trust you can leave her for. Always. The sands of time wear on everyone, but young men, the numbers game gets better for you. A potential strategy is take her back, and then use her being high on the ladder to get you a new, hotter girlfriend. Women love the taken, off limits guy, so use her as pre-selection and get out of there.
The Ladder Theory is an old one friends and I used to discuss and refine like the Wave Theory or the old Internet idea, the Deacon Effect. I bring it up after the wonderfully race baiting, dark post by Heartiste yesterday. Yes, horrible stories like that are wretched enough for unrestrained female behavior, but instead of just pointing and shouting "beta" at the guy, figure it out and how to stop others from making the same mistake. The beta in the photo was a normal looking 18 year old. He does not know yet that the relationship is doomed but that he'll recover and do better. Guys fifteen years older with Faceborg profiles can see the ones that thankfully got away. You can spin just about every break up with a crazy woman in your favor. Regular Joes and professional, millionaire athletes can make the same mistake (twice). Do not tolerate bad behavior. This is a lost cause but hopefully, it reaches one guy out there. The next one would be "don't tolerate fatties", but that one is hopeless too.
