sorry it had to come to this but i think maybe you are helping him more than you or him thinks. my family took the same kinds of actions with me and no i was not happy about it at the time. my addictive thinking was that they were being mean. i soon hit my bottom and realized that they were helping me by helping themselves.
today i'm clean, sober and totally grateful to them for making the choices they made. today we have an even better relationship than before.
i pray that your son finds his way soon.
