Hello Sher
My son is also the addict in my life. A little younger than your son, at 29.
He has veen in and out of prison too, over the last 9 years, and always full of good intentions for when he gets out. I have seen him once, in 3 years. I have minimal contact with him via txt message and a rare phonecall. If he starts the relentless requests for money, I block him for a while.
i dont think this is harsh. Its something I have to do to protect my own well-being. My son walks his path, and I mine.
We can't waste the rest of our lifes trying to help adult men, who don't want to be change.
We are important, and deserving of peace and joy in our life. Hang in there!
Much Love
