<human>: I've done some pretty shitty things in the last year-  I have let a very good friend down in too many ways to count. I cut this person out of my life and kept some very important information from him. 

We have not spoken to each other in several months and he has since moved away to I don't know where.  Though it would be easy for me to find out where he is since most of my friends know, I have not asked because having him out of my life was my choice (one that I deeply regret) and he chose not to tell me (and I respect that).  

The reason I wanted him out of my life was simply because of his drinking habits (long background/history supports my dislike of alcoholics in general).  I want to know if he has stopped drinking.  He told me a few months before he moved away that he had stopped and I was incredibly proud of him but sceptic. I know that he has quit before and fallen off the wagon.   

I need to know that I was wrong.  I need to know that my once close friend has been able to stay away from the drink that he so desperately wants.  I want to know more than anything that his life is going in a good direction.  Do I have the right to ask a friend how he is doing?  I just want to know if he is still sober. I need to know that I was wrong for losing faith in him. 

I would also like to know if he went back to school as this was something we talked about a lot, I'm just curious and don't need to know this.

Condense the text into a few key points
<bot>: Let a friend down, we no longer speak, I want to know if he's still sober, do I have a right to ask our mutual friends?
