Guy leaves home.
Guy marries woman.
Woman gets bored.
Woman leaves.
Woman takes half of the man’s salary.
Man moves back home with his parents.

You are on the right track, but have left out few items of significance. I will add a few things in no particular order.
Career track employment is hard to find. This increases the uncertainty factor for young males in making a commitment.
The available females in many cases already have a kid or two, by other guys. This increases the uncertainty factor
The family courts are openly hostile to men. This increases the uncertainty factor.
When planning for the future one needs a level of certainty of the potential outcome within what one can control. Super high risk, with high potential for negative outcome that can last for decades leads most to not place a bet.
