Yeah My boy is and example of this not being true, dude is simpin over a chick that is over 200 pounds with 3 kids. Not only is he giving her his money, taking care of the kids and dealing with the exe's that are still in her life. She doesn't even really claim him.
He's been shot down multiple times by this chick ( she wants a sugar daddy) and is doing all this in hopes that she doesn't leave him.
Why?
Your guess is as good as mine, the ultimate sucker. Me and others have told him over and over.... his response? "I can't help it"
Any decent man worth having aint gonna want to take care of someone else kids. One kid, sure...multiple kids....nah
Maybe once your in your late 30's or mid 40's... but before then. I can't see it.
