I was raised to believe in making family, in treating those without family or social support to whatever comfort and accomodation that can be mustered.
I tried to be a friend to an old beau and it backfired. Turns out he was a useless narcissist, concerned most about himself, but in particularly self-destructive ways.
I treated this friend to a room at the beach for over a year, rent-free. He reaped many benefits from having no rent to pay, because rent in this complex is $2370 for a 1 cama, 1 baño, >600 sq feet. He reaped auto insurance discounts. He spent money bingeing on gentrified coffees, avocado toast-type crap, smoked fields of weed, ate tons of processed foods, drank Monsters and off-gassed that funky taurine every night. He spent money like water, ran up credit card debt, lost something every day, and generally created tension and confusion in my home.
He saved no money and burned his bridges here, so now he is outty.
Human beings can oftentimes be most disappointing.
