Don't cry, it just is what it is.
I've been on both sides of addiction. An addict, and also someone who loves an active addict.
One thing that I've learnt, (am learning), especially from this site - is there's nothing you can do, for anyone else, except yourself.
Set some new rules, boundaries, with your love. If it's meant to be, it will be. Example - don't come near me high, or drunk. If he wants what you want, he will seek recovery. If not, all you can do is wait, and wonder if that's what you want to do.
Good luck, everything above, is what you need to hear, the people here are all so wise, and supportive - and they've really been there. They're not just giving advice, deduced from tv, and the media, they've all had someone rip out their hearts, and parade around like it's all about them.
Take care
