Had a conversation about this with a homegirl of mine years ago. She said she refused to date a man that made less than her because "she already raised one man, she ain't gonna raise another."

(referring to her son)
The man also had to be above 6'0" (she was on the taller side), fit, *** drive that can keep up with hers, etc etc etc.
I informed her that she's talking about a very small percentage of men.

She didn't want to hear it.
I also informed her that she is ruling out many professions. So you won't date an educator, most firefighters, cops...
Her response...
"No, I'll date a cop if he does overtime. They make a lot of money."
Never occurred to her that

A 6'0" attractive cop who does overtime is not going to be around, and likely won't commit to you anyway!
Again, not trying to hear it.
Fast forward... after countless failed dating phases, she ended up with a 5'8" juiceball who had 2 young kids and massive insecurity, jealousy and control issues.

They never learn.
