Welcome to Sober Recovery.
I am the mother of 2 addict sons, one is 29, and sober, the other 34, and still using.
What I have found out through the travels of addiction is we cannot love them into recovery.
Your son, sure sounds like he is in a downward spiral. As mean as this sounds, I would not try in any way to prevent it. It's a continuous circle, we help them, they stay somewhat sober for awhile, then the circle starts again. If your son is down and out and spiraling down towards his bottom, it may be a good thing.
If he refuses to come home, I sure as heck wouldn't force the issue, although I realize you are trying to "help" him.
Have faith that your son's Higher Power will lead him where he needs to be.
Hugs to you,
I know how hard this is.
