Another word of caution....
By all outward appearances, this young man seemed to be very well adjusted. He has many long term friendships that spent a lot time at his house, a long term healthy relationship with his still current girlfriend, his grades were always very good and was very active in sports.
He was always open to talk, he had a lot compassion for his dad, embraced him during recovery and was broken hearted with each relapse. He also never wanted to move out, he was still living in "hope" for his dad.
But the effects of living with an addict took its toll. The long term effects have manifested.....well after they moved out. So heartbreaking, so very sad!
