He wants to hire me as a talent scout when I leave rehab, but is willing to pay for my recovery home once I leave rehab. According to him he's "Dummy rich, an anarchist, and was saved by someone in the same way" in the 90s. Can I get fucked over by accepting this dude's help?
Can't speak to if he is being genuine or not, but if you have had bad experiences previously don't fall into the trap of being unable to accept help. Be wary about signing any contracts and try to keep other options open. Best case scenario looks great, so try to mitigate the worst case without falling into the trap of not accepting any help at all, which would continue to hurt you throughout your life.
