it could be that he just likes donuts now? in the big picture, that's a pretty tiny thing to be focused on as the barometer for the soundness of one's recovery.
he hasn't drank in almost a year.
he goes to a couple meetings a week.
and he has a donut now and then.
that's not really IT, is it?
you were expecting MORE. turns out "if he would only quit" isn't the solution you were hoping for. you didn't like him much as a drunk, and so far you are underwhelmed with him as a sober person.
look at bit less to him and more to you for your answers, assure your own happiness!!!!
