Beautiful story and your excellent articulation made it all the more better. I also noticed this recently. A friend of mine who qualifies as what's called a "f*ckboi" is depressed and lonely within.
He cannot get along well with people, is always complaining and his facade to get laid is just a coping mechanism.
After some reflection, I realized how another friend of mine was the exact same.
It's funny how at one end, there are weak men that cannot even make eye contact with women and the other end, weak men again that get action constantly and suffer from loneliness.
