Who suggested walking away? I suggested letting go of controlling other's actions - that's not the same thing.
"Living serenely", to me, does NOT include "tiptoeing through mine fields and atom bombs".
Truth is, no addict "knows how to recover", which is why so many resources are available if/when they are ready to reach out.
It's nice for him, isn't it, having all of you at odds over him while he happily drinks away? Do you seriously think he is incapable of saying No? Or is it more likely that he doesn't WANT to, but is willing to say whatever it takes to make you happy at the same time? Of course that's illogical, we're talking about full blown, advanced addiction here.
