I would guess that many men in the age group discussed in the article are living with a woman out of wedlock. No one wants to commit to permanent choice. I think they call the lack of responsibility “keeping open ones options.”
Keep those options open long enough though, and you’ve got bachelors who get sick and then try to marry into free nursing care.
I think it’s in many cases the gal is on welfare if, kids are involved,.....so they live together rather than marry so we can pay for the kids to have their mother at home.
New neighbors are doing just that and planning on buying a home in a year while they save “Our money” to do so.
