I do believe that it would help to be away from the temptation up here & negative influences, and old routines.
do you also have an addiction problem? or are you trying to manage HIS?
if you very much want to move but he does not and you choose to NOT GO for him, you are setting yourself up for resentment. he is in a very fragile state right now and shouldn't be thinking too long term. in fact he seems to be trying to keep it simple. he has a long ways to go and it will be HIS bus to drive.
if the beauty and the peace of the place called to YOU - answer it. go or don't, but don't make YOUR life decisions on what you think might be best for someone else.
