Nietzsche said "Ah, women. They make the highs higher and the lows more frequent", I think this quote encapsulates the trajectory one finds in a relationshit with a woman.

You get the honeymoon phase where it'll seem like she's NAWALT but as soon as that lust dies off the male finds himself in a predicament, he realizes NAWALTS don't exist and that this will be it, consequently becomes roommates that occasionally performs a 20 minute exercise with a sticky ending as Colttaine so eloquently put.

Man's next project begins now after the disillusionment of the NAWALT, that is his fruit(s) of labour after repeatedly performing the aforesaid exercise with the AWALT. He wants to be a "good" man for his family and that means being a disposable utility, a draft horse with a dangling carrot in front of him that he himself has placed there because the capacity a man has to delude himself far exceeds any women's hysterical incliniations. Whether it's for war, family, friends or oneitis he can very easily turn on the aspect of being a disposable utility as easily as pushing a button (Of course there's a hierarchy of priority where women reign at the top).

After working overtime to satisfy his AWALT's demands he reaches an equilibrium of respite 18 years later when the offspring(s) have left to undergo the same monotonous process. Now he has a few years left if he hasn't been divorce raped already (marriages end in divorce in less than 5-8 years), and besides him and his AWALT most likely don't sleep in the same bedroom and even if they do I'm sure he isn't thinking "last X years was so worth it" just for this moment in the bed.

Basically dead bedroom man spends all his time in his mancave while his AWALT likely getting it on the side.

He later slowly fades away in the background with no time left for himself at all from the start of the relationshit, middle and finally end right before oblivion with the pleasant knowledge of being a useful tool for his family, offspring(s), society, etc.

This is the life of your average man and has been for a very long time. Regardless of whether MGTOWs think that's a life worth living or not, for me this isn't something worthy to aspire to.

The allure of love, soulmates, family, children and all that lovey dovey stuff doesn't correspond to reality when we look at reality from a scientific perspective. Yes you need to have a certain predisposition to comprehend reality this way and I bet most MGTOWs do, not to mention 90% or some absurd percentage of Americans believe in these fairytales inferred from Colttaine's vid but then again everybody lies and expect others to lie to them to make them feel good, Jung's collective unconsciousness might just be that, lies people participate in to feel good about themselves; more info in Stardusk's vid "Price of lie".

(If you haven't seen it yet then do yourself a favor and watch it now, one of this best!).

Bluepillers or even many MGTOWs might disagree because they think love/relationshit is a gestalt, meaning it's more than the sum of its mechanical parts. When you ask them to justify it, they can't in any coherent, cogent manner as to why it should be viewed as a transcendental thing that's beyond the reductionist approaches of science, maybe for the "greater good" aka: disposability of men is required for society's sustenance.
