Hi and welcome. From the sounds of it you are going through a very hard time. But overall, you sound like a nice person and a good mom. He has a serious problem that he needs to take of and it's good he is trying to do that. Try not to worry about him falling in love with someone else. He is likely just concentrating very hard on his recovery and that is taking up a lot of his time. People in early recovery don't feel too sociable and outgoing sometimes. They are battling with it and it's not easy.. Take care of yourself and your daughter the best you can and be good to yourself. I know this is hard, but you can get through it. It will be alright.
