The official guidelines, at least in US, is to isolate at least 10 days since first symptom started, or 10 days since testing date if asymptomatic. If you are sure that your wife was infected with the same virus type as you (getting from the same source), then you are free to be in contact with her; since her body still has that immune system.
If you'll be in contact with high risk people, then I suggest to get retested by the end of 10 days, or to isolate for 14 days (and meet those conditions I said on early post). If not, 10 days seems like the magic number for isolation.
