Hello Frand my name is allen moser and i am 23 years old, i know i am kinda young to be giving suggestions or advice, whatever you call it but i am a recovering alcohlic/drug addict and i am a chemical dependency counselor and i would recommend that you should never give up on him for any reason at all. the reason i say this is because he does not live with you and you are not enabling him whatsoever, so whenever he does call if i was you i would just tell him that i love him and it makes me sad to see what you are doing to yourself. that is what i would do, i wish you the best of luck my friend and i will pray for you
