Hi jewelstar, so sorry you are going through this. He could be drinking again; it could also be that he simply is too early being sober that his attitude has not been modified yet - from my understanding, the first few days (maybe longer, I am not sure cuz I am not an alcoholic) there is a lot of anger because they can’t have what they want - which is to drink. I went through this with my recovering AH. He was more nasty than ever the first couple of weeks to a month after he got sober, and made me question if he had quit and I found myself looking for the evidence again and then I stopped and started to move forward with my life. It was not easy. But you need to look out for your welfare and the kids’. Obviously he is not going to.
Take care and hugs to you. Keep posting and I agree al anon may help you...
