Please do not take this wrong, but sorry to tell you this, sounds like you are codependent... you have enabled him on many fronts...
His issues are way bigger than what you can handle on your own... my wife discovered that finally when she was trying to wrangle her addiction herself... it required professional help...
For her, it was detox, then right off to a rehab... there was no coming home to test the waters of normalcy again (she spent one night with the family between detox and rehab because of availability).
Save yourself the drama of this relationship... go no contact with him, and that means his parents also. His life is his and yours is yours... they are not connected in any fashion and it would likely be best that it stays that way.. for both of you.
