This. Decent people see the children and know what to do. Idiots empty their balls and run away.
And harpies find a well meaning sap to pay for their spawn forever. I talked my mate out of getting financially involved with one a few years back. At that point she had 3 kids with 2 fathers. She now has 6 kids with 4 fathers.
I don't entirely blame single mothers who go "gold digging". They may not even realise they're doing it. But I think if I was to be financially struggling and meet someone who was not, even without being conscious of it the financial stability would appeal to me.
