My husband recently found out about the extent of my drinking and he's tee-total. I was so, SO embarrassed and ashamed and didn't want to talk to him about it. I went to an AA meeting the morning after, shared and that night had a talk to him about it and told him I was back in AA and felt pretty good about it.
He doesn't know why I go there and thinks it's not needed for me because he is definitely of the opinion that drink and drug is an "indulgence". He doesn't preach or make it hard for me, he's supportive, he just doesn't get it, and he doesn't need to. Just being there is enough.
