Lbl, asking the Universe to keep blessing your family.
It was two years before we belieed Daughters transformation was real. We were afraid and jaded and had been fooled and lied to. The good days turned into months and then years. On her own, jobs, college (took out a loan and ask if I cried at graduafion!), her buying a home with SO, her precious baby...getting back her healthy glow and normal weight. She never told us "I am quitting." She just did it. And it scared my mommy heart. I was afraid, like so often before, it would all fall apart in one day. But it never did.
You are doing this in the very best wsy in my opinion. You set strong boundaries when he is still very young and not steeped in addiction for a decade or more. I believe it is easier for them to change while they are still very young. That often we are afraid to hit hard on a teen or young twenty. But the young age is a pliable age. The older they are on a rough path, the slower changes happen.
You had so much courage. Not had. Have. Yet you have always operated from a place of unconditional love. Your son sees this, knows this.
I am crossing every body part I have that this sticks. Honor today, now, by doing something very nice for yourself! Tons of love and light!
