I attend CR and have heard many testimonies. I have heard a repeated theme in several of these. They went to rehab 3,4,5,10 times and immediately relapsed. Only when they spent some hard time in jail were many of these people (so many I see as kids, early 20's) did not ever get clean until they went to jail. I have watched their parents suffer, however I have watched them come out on the other side as having learned a hard lesson. Not every time, but many. It has been their only motivation to get clean and stay clean. For some they pay it forward and work with other addicts.
I cannot tell you this will happen, ultimately only he knows, and right now I doubt even he knows. You have alot of time to think and learn in jail.
You are in my prayers.
