Hi BB
Being in a relationship or loving a relative with alcoholism is frustrating. The thing I have recognized though is that there never seems to be any 'closure'. You never seem to know what will happen, if they will recover, if things might be different. No promises, not remembering, no commitment, things we probably would expect.
Your boyfriend right now, is not available to you whether he is trying to recover or not. Sometimes it just isnt about whether they love or miss you, its about their addiction. Yes, he could of responded to your note but he may just be so far away from reality that he just cant, who knows. Its hard when we cant get closure, but this addiction is a lifetime thing for him. BB, look after yourself, try not to worry about things and Im sure in time he might contact you if he gets to any kind of recovery.
