Congratulations on making a good sound decision for your ongoing sobriety.
If it is only your first or second time quitting, then as a woman I think he is being a little cold. If you have tried quitting many times, then maybe in his mind it is like "same old song" and he is just going on about his life.
This kind of detachment is what those of us in recovery for codependency learn over time, to be able to go on about our lives and hobbies regardless of whether the alcoholic is still drinking or not. Basically, we learn not to make another person the center of our world.
