I don’t risk my own self and life to give people with a history of making crappy decisions “chances”.
I will offer assistance if I am able, while maintaining strong boundaries.
With one friend who had drug issues and kept getting involved with really bad people I would gift her money, move her things, get her into shelters. I never allowed her to stay with me or even be in my home because she had a history of theft from family and friends. I eventually got the call that she had been shot and killed. Sadly, my greatest feeling when that happened was relief.
Another friend with mental health issues, I would gift him money, move this things, even store his things, intercede with family and law enforcement when necessary. He eventually behaved very badly and almost got me fired from my job so I dropped contact with him because his behavior was threatening my own survival.
I am now learning to have better boundaries with this sort of person and try to identify and not get involved with them in the first place.
