Hi Autumn, this is a very common reaction to sobriety judging from the thread on the F&F forums, in fact it's a good sign for his recovery.
His mind has been used to alcohol to filter out normal life. It's going to take a while for him to cope without it. As an A with a long term recovery, I'd say it took around a year for me.
I suggest you step back, give him plenty of space, and work on other aspects of your life like hobbies or family. Hopefully he'll return mentally when he's ready.
