Welcome to the Forum Mamamacx!!
Within the first 6 months of Sobriety, all I cared about was not having that 1st drink, my mind was soo obsessed with getting to bedtime without drinking and a lot of things went out the window, relationships with family/friends almost disappeared and were rendered to simply saying hello each week as all my energy was being put into my main focus of Sobriety.
I wouldn't take things too personally as your boyfriend is going through a lot of changes, physically, emotionally, mentally, learning to live and adjust away from alcohol can't be done overnight, this is a longterm lifelong journey, but it does get easier with time.
I'm sure there are others that can give you some specific advice on having that exact same situation themselves, all I know is he is going through a lot at the moment, but with time things will adjust for him!!
You'll find loads of support here on SR!! Great to have you onboard!!
