My cousin is a coparent in a polycule of 3, but she is not the biological parent of their children, she is the default parent though, as she is a SAHM and the other parents work. They've been together for 23 years.

Half my family acts like she doesn't have any children, and that she's some sad single live in nanny. They will ask her how her "room mates and their kids" are going, even if the "room mate" is standing next to her with his hand on her arse and has just finished telling a story about how in love they are.

My dad is also thinks I have "no real bills" because I don't have a mortgage. He says rent isn't a real bill because it's not like the bank will take my house if I don't pay. History opinion on evictions is "that not the same, because you can get a new place to rent that night, you can't buy a new house in a day"

My rent is 6x more than his mortgage and I don't know anyone who could get approved for a rental the same day they get evicted for not paying rent, but sure dad, I'm rolling in expendable income over here.

Some families are weird about denying how their relatives live.

But it could also be that she calls her cat "her baby" and lives at home with only personal bills.
