Every person is different when they come out. Some work their program with enthusiasm causing family and s/o's to feel left out, some are angry and resentful, some are just overwhelmingly happy. It all depends. The important thing to remember the A is going through a lot of emotional and physical changes. It's hard to deal with sobriety for some. Be loving patient and understanding and perhaps in the meantime you can join an Al-anon meeting for yourself to be better enlightened as to what to expect.
I think you both are making great strides in the healing of the relationship. When addicts and alcoholics go into recovery in some aspects so does the whole family. Take it slow, keep it real simple and don't expect miraculous changes. Good luck, keep us posted!
