There's no rush on love, is there?
If he's the one, then the relationship will continue to work with him living wherever he is for awhile.
There's a huge transition in thinking post drinking. I might ask this question on the alcoholism forum--how much they changed their lives. Many people completely rearrange their lives and find dissatisfaction with their current SO's and breakup relationships. I wouldn't want this to happen to you while he was living with you. I also wouldn't want him to relapse in your daughter's presence, and the danger of relapse is highest in the first year of sobriety.
I would first want a stable home for my child. She's already been through one major upheaval in the last year.
You can put it all on you if you want to postpone living together. You can say that you need more time alone before you are ready for cohabitation.
