You and I must have been in opposite threads there. Because it was weird, but in the opposite way you're describing.

Once saw one where I guy's wife let her sister something close to 1% of their savings because both the sister and her partner had been laid off in one month. The guy went ballistic and move everything out of their joint accounts into ones under his name only, and gave her a strict allowance. People on reddit were telling him that's nowhere enough, he should apparently divorce her right away, and maybe sue her.

They were also convinced that because of this one short term loan the SIL and BIL were now going to think he's a sucker, and they'd move in.

It was weird. Those places often get weird though because people in healthy relationships, or single but happy about it, just don't show up. So you just gave a cycle of people unhappy with their personal relationships goading other equally unhappy people.
