G.B.
I would think that as an adult he needs to grow up. My daughter is 32 and is finally an adult. She grew up in rehab, she graduated out in October...
My thoughts....
If you boot him where is he going to end up?
With good friends? With drug friends? In a shelter? At a girlfriends home with her parents supporting him?
Aren't there any other options of what to do with him? Perhaps he needs to get enrolled in some college programs. Does he have any interests? I feel so bad about how I treated my daughter on so many occasions.
She would call me with no place to go and want to come spend the night. I would say no, the kids could come but not her. So she would bring them over and then go trade a place to stay for sex, eventually she was selling drugs for them for a place to stay. Then they started giving her drugs for selling them for them.
His life is worth a final effort. I don't know what to do, seriously wish I had words of wisdom to pass on but I only know the bad side of how it can work out. Please just sit down with him and talk, listen. Ask him what he wants to do with his life. If he truly does not know then offer the opportunity for him to go to a college and visit with a guidance counselor. They may be able to ask the right questions so he can get a glimpse of what his life could be like if he would just try to manage it a bit better.
That or take him to the nearest branch of the military and drop him off and then block the doors so he can't get out...lol.
