I don't know about the world at large, but my husband, I can tell you his issues.
Living with him is like living with a child most of the time.
He never holds a job long and when he does make it past 6 months he starts self sabotaging it.
I tried to be a homemaker as that role fulfills me completely but he won't allow it for long.
He will bitch and complain that we need more money and when I've heard enough and go back to work he quits his job within a few weeks every time.
Whether I am working or not I am still the one who cleans, cooks, takes care of him, of anything needed done, and takes care of our pets.
He will spend all his time playing games, getting f*d up, porn, and sleeping.
He never picks up after himself or does anything I ask him to.
If he does it may be months later after asking and then it is done begrudgingly.
Sex?
Maybe once every 2-3 months if lucky.
I'm sure his hand gets more sex than I do
He has been like this since the day we met and when I was in my younger days that was fine but I grew up.
We are now in our mid 30's and nothing much has changed.
He lies to me and everyone else plus he steals from places he works and lies to me about that too.
Then he gets caught and fired and places the blame on me as to why there is no money.
I can tell you with 100% truthfulness that if the world don't end and our species continues on then the next time I marry it will be with an older man who is mature.
In fact I would urge all women who are dating these man boys to please reconsider.
Take it from me and learn from my mistakes that it will only bring you pain in the future.
Marry someone who can and will take care of themselves not some boy who is only leaving one mamma for another.
