I just don't understand this turn around in his behavior because he was so pumped up about going and was excited all the way there.
I tried to put myself in his shoes and all I could come up with is, he's been in recovery for two years now, and this may feel like punishment instead of self-protection. Maybe a gentle reminder might be helpful, that his brain chemistry needs time to adjust without temptations, not necessarily his behavior?
You and your partner and in my thoughts and prayers.
