This is a difficult one, Greg.
I spent 10 years in AA, and there is something that I heard a LOT whilst I was there. If the rehab he went too was also 12-step based, then he has probably been hearing it since the day he was able to function in rehab. That was that previous drinking places, and people, should be avoided at all costs because it might lead to a relapse. It's about staying away from dangerous situations, and therefore staying away from that first drink.... or any triggers caused by that sitaution or person that might cause drinking. It is suggested to new AA attendees that there is NOTHING more important than their recovery because without recovery, the rest will be lost at some point, anyway.
There are many partners/friends of drinkers that have experienced this from their drinker. And it's hard to cope with because whilst drinking used to be the thing that consumed all the thoughts and time of their partner, now it is the need to do anything and everything to stay sober that consumed all their thoughts and time. The relief of their partner finally seeking help and coming back to them, is soon dampened by the 100% focus needed on 12 step recovery in order to remain sober one day at a time.
In terms of the making amends part of the 12 step program, this does not have to be done face to face. In fact, if you have moved on by this point and do not want to risk your feelings being confused or awakened, it is perfectly acceptable for you to text him and advise him that you are going to move on (or have moved on) and do not wish to be part of his amends process. Do not worry - this will not affect his program. For whatever reasons, some people don't want to be part of this again and the only requirement for your friend is to be 'willing to make amends'. He can demonstrate his willing to his AA sponsor by writing a letter to the person he is trying to make amends to, but not send it and read it to his sponsor instead.
If you look at the 12 steps, step 8 is about making a list of all those we have harmed and be willing to make amends to them. Step 9 is to make amends to them, unless doing so would injure them or others. Believe me, there are plenty of people who have no desire to ever be in contact with a drinker ever again after all the pain they might have caused them, and reject the request to make amends. Do not feel obliged to be in touch with him again if you have moved on again. It is rather arrogant for him to just assume that you will be happy to accept his request for contact then.
At the moment, everything revolves around him and his recovery in the same way that it used to revolve around him and his drinking, and sadly there is little you can do about it. It is probably neither of what you think, either ignoring you or binning you - it's just recovery, 12 step style.
