James, do not continue to pay for his phone.

Let him do what he is going to do.
You really cannot control his actions or "save" him.

I think you know this in your heart, but feeling scared to lose
contact is natural. You asked if paying for his phone is enabling,
and I would say it is. He is an adult. He took the 80 dollars and didn't
replace it as he said he would

You can see very well where this is going. Be strong
and let him stand on his own two feet, or not.
It isn't yours to carry.

I forgot to say

If we could save our addicts through will or love
there would be no need of a list like this.
You have to take care of your own recovery
and leave him to manage, or not manage, his own.

You deserve to be loved and respected,
and since he is an adult, he deserves the respect
to find, or not find his own recovery without being
managed like a child.

If he wants a phone, let him work to pay for one like you do.
I know it is hard. Try to hang in there and don't contact him!
