He could be giving a very accurate description of how he feels. There is no way to know.
My husband has been in recovery for 16 months. Personally I suggest that you not focus too much on individual conversations but let time go by. Most likely there will be ups and downs. If you focus too much on how he is doing you will go crazy.
Focus on yourself. If you don't journal, consider starting one. It can be really interesting looking back on your own development during the recovery process.
