Hi and welcome Maddie
Unless he's saying these things sober, and saying them repeatedly, I wouldn't put too much store into it - especially if the relationship is largely a good one
When one partner finds recovery our partners have to readjust to the new us...give him some time...and give yourself time too.
It took me 3 months or so to work out the parameters of who sober me was.
The things I thought were huge unsolveable problems in the beginning didn't seem so bad a few months later?
