I made a couple of decisions early in sobriety that I kind of regretted later. I wasn't thinking clearly enough yet when I made them (about 2-3 months in). How long have you been sober? How long has he? Some people take longer to forgive and trust again than others. My best friend/kind of boyfriend held resentments for a longer time than I thought was reasonable. We really struggled and I cut off the friendship/relationship in frustration, only to regret that and rekindle it. He did come around eventually, and things are fine now. Maybe your SO needs some more time? Have you thought about going to Al Anon? You might take some comfort from talking with other people in relationships with alcoholics/recovering alcoholics. You might gain some insight. And like DriGuy said, you may want to do nothing for a little while, depending on how long you have been sober. Unless, of course, there is abuse happening now, in which case, take care of yourself immediately.
