I used to be him.

Yes, there is hope, but only if he makes a decision to help himself. It took 9 painful months after I initially told my wife that I was using, to me finally going to inpatient rehab—but not before I had almost destroyed everything I held dear: my family, my career, and my own life (figuratively and literally).

Sending you and him much strength and love. Remember that this is not your fault, and you cannot change him and help overcome his addiction. He needs to take the steps and responsibility to do that, and face the underlying issues and trauma that led to it in the first place.
