Personally I would hold off for a long while. I think the stress of amalgamating two families could make her recovery very hard indeed and possibly give her an excuse to start up again. That would not be fair to the children involved as well as yourself and her. My boyfriend of over a year asked if he could move in with me recently but I said no. I am not recovered enough after 3 years ( I wasn't the alcoholic) and my kids are still adjusting even tho they are 18. She could get another rental for the time being. Kids can move school or travel on the bus.. It's not insurmountable in a year or so. Or she could rent nearer you. I'd give it time to see how things pan out. You are already not that happy about some aspects of the new her and more things could come out over time.
