I am a recovering addict/alcoholic.......I've been to treatment 7 times, once my insurance paid, the rest were community based, indigent, scholarship, freebie, low monthly payment type programs. My folks did NOT ever pay for treatment for me. As far as you finding the halfway house.....NOPE, my suggestion is don't do that either.....there should be resources his counselors at treatment can suggest to him. Let him do the checking into that. Just be firm about he can NOT come stay with you....
Hugs & love....BTW, it took 20 yrs for me to have these 10 yrs clean & sober that I have now!!!!!!
