I am in the same boat you are. It is stressful getting sober, and emotions I have suppressed for years surface. And now they have to actually be dealt with which is frustrating to say the least. When me and my boyfriend met 3 years ago I was deep in addiction so now that I am sober I am different, and sometimes hard to deal with. I think it is just difficult for someone who is not an alcoholic to understand the roller coaster of emotions that come with getting sober. I doubt he doesn't like who you are now he probably just does not know how to deal with the new you. Give it time.
