Let's enter THE GAME OF LIFE
I see, you are thinking at the primal, and carnal level point of view. But for women, it's much deeper than that. It hurt you that she fell in love with him, because she did not see it only as a biological carnal need. She it as something more. Women cannot separate their emotions from their actions because they are emotional beings. They think with their hearts, and not logic.
When women manipulate men by gaslighting (it's your fault I fell cheated on you because...), or trying to get something from them (promotion, louis vutton bag, prada, money), they are manipulating them.
When a man uses positive reinforcement, it's much more simpler than that.
Good behavior is reinforced by a compliment ''I like that'', or a treat.
Negative behavior is punished by silence, ignore, leave the house, leave the woman.
The punishment works because the women of these times are rarely if ever punished, and held accountable for their actions.
In these instances the man is giving something, either a reward with a compliment/a treat or he is handing out punishment.
In the instances where the woman is manipulating the man, she is taking from the man, either materially, or making him doubt his reality. She doesn't feel guilty, because they teach her this in magazines, and online articles, like it's normal "Use sex as a weapon to get what you want".
Where does the man take from the woman? He gives rewards. He gives punishment. It is people management. You can use this exact same method to work on everybody, and to treat you with presence, and respect.
I'll oversimplify this strategy:
Treat people who are nice to you, nice.
Treat people who are bad to you, bad.
Don't give them the time of day if you have to.
Anything more complicated than that is female territory.
This is how the game is played with everybody now.
Even by not participating in this game, you stand to lose everything you know and love, because you are unaware, or lack the skills for the game of life.
Even when you think someone is loyal to you on a spiritual level, think twice.
Again, don't trust a girl, have fun with her, and when you're bored with her in particular tell her to leave.
This way you won't need to stray, you can do whatever you want. Even if you agreed to an open relationship, she will take your seances with other women as a sleight. That's just the way it goes (how women think), on the outside they may humor you, but inside they are plotting how to get back at you. Sounds familiar, doesn't it? When you were talking about Japan being a matriarchal society, you were right.
Do you know why women want open relationships? Because they know they will be the only ones ******* multiples partners on average. As soon as a guy gets another girl, the main girl shuts down (or tries) the open relationship.
They want to have their cake, and eat it too. You can't have a side girl, only she can have several side guys.
Even a handsome man, won't have as many suitors as a 6/10 female.
Even the girls that used to get turned on when you told them about other ladies change because of their hormonal biology, and will start to resent you, so much so, that they will find someone else on the DL, because they will conclude it's not fair. Even the swinger ladies. You may think it doesn't make sense, but that is how women function, outside the realm rationality.
Women keep secrets for power. A woman will feel like she has the advantage over a man if she keeps secrets from him. Supposedly, it's all about the empowerment. 48 Laws of Power can confirm this. The reason why she didn't tell you she kept seeing the other guy, was because she wanted that power over you, it made her feel stronger than you. Why? Women are just power hungry, or out to seek revenge.
Women are rarely ever the same within two moments. A woman's behaviour is like the waves of the ocean, not one wave is exactly the same.
Us men, we are logical, rational creatures who prefer predictable outcomes, that's why we will never completely understand the rules, surprises, and blindsiding situations that women spring on us, and the hamsterings they live by.
It doesn't matter how good you are, it doesn't matter what family you came from, what company you run, women will still cheat no matter what. Even with the guidelines of positive reinforcement, they'll work if the girl is into you because your value is high. As soon as there is a slip, or weakness, that's when you can expect her to step out.
There's no equality. Nowadays, women are raised to hate men, and envy them. Society is rigged to belittle men, and denigrate their legacy, and the civilizations they built. And what are men doing? They're receiving texts from their wives on a date with a handsome stud, she's describing how they are going to do it after dinner. #cucked
To understand more about the game of life, I would suggest reading Robert Greene's book The 48 Laws of Power
You may have to read it a few times to internalize these laws, and use them to your advantage.
There will be many ''I should've done this'' ''Aww shucks, I didn't know that... That's why...'', and many enlightening moments.
In a way, women are like mother nature: unpredictable.
