I believe men who actually DO wanna evolve might underestimate this topic.
Most female behaviours that work AGAINST you as a man will be better to understand once YOU are on the other side of the fence.
Let me explain; its easy to stay faithful when you have no options. And I don't mean " incel no options" but rather not how a HOT women has endless options from men who are willing to go all in to get her / take her away from someone . Im not talking " making an OLD profile and go through the trouble / approach 100 women get 3 numbers" options. I mean literally just existing and getting p00sy offers left and right.
To adress the bold part; if you approach a level where multiple women want you ( aka love bomb you simultaneously) you will get the real test...if a prime Megan fox flirts with you every day, it becomes a different ball game innit?
Lets look at cold female behavior; we all theorised that of a woman goes cold there might be another bull in the ring. But only after you've been love bombed by a new hb9, you will understand the exact dynamic behind divided attention( a new COW in the ring for us men) . It's a new shiny toy that swoops up all of your attention. Let alone if you would get new shiny toy approach you at least once every week like how hot women experience life..
Integrity been mentioned and yes I agree. But Integrity is also a feeling that might and often will change because the rest of the world doesn't necessarily have the same level of integrity. Arguably integrity in love is the same as naivety, the most important ingredient to make an LTR work.
All throughout history men have been cheating with younger hotter women given the opportunity.
TLDR; be( come) as bluepilled as possible and stick with it. Any drop of redpill mindset might push you towards believing that if she cheats on you one day, you unnecessarily missed out on great sexual experiences...
Not the nicest way to put it but hey...life aint fair..
