"DollyDo- Thank you for your words. I have one question though- what does that mean to love him from afar? "
You do not have to live with someone to be in love with them. He needs to find his own way out of the hell called "Addiction". Sometimes, love means letting go, one can actually "love" a person to death. Enabling and allowing the addict to have a soft place to land, is not the answer, in fact when dealing with an addict, it is counterproductive and only keeps the addict from reaching their bottom.
I know that you are in pain, however, try to accept the reality of the situation, you are not helping him or yourself, as it stands now, this is a no win situation. When and if he is ready, he will stop using and get into a recovery program, this will be in his own time and on his own terms.
You sound like a good person, be good to yourself, let go.
