Cheapness of sex is only one part of why men are backing out of the very bad bargain of being with today's women. When you add up the cost benefit analysis of marriage and recognize how women behave in our gynocentric society that treats men as pack animals it's not even remotely worth the cost. 

I was married but just made the break early and before the arrival of kids. Marriages have a very high probability of a wife initiated divorce the longer they go.  Once divorced there is an even higher chance that as a man you will be stripped of assets you built, income you earn, your children and your dignity.  Bullet avoided.

Our laws, social norms and institutions are now designed to cater to women, remove their need for accountability, and treat men as cheap and disposable.

Men, stop living to make your woman happy. Live for yourself. 

Build your character, become a better version of yourself, find your own purpose and go make it happen. Leave the world of women behind.
