My husband had the stomach virus recently. he is 72 hours symptom free. i have bleached the house twice now. when is a good time to go back to our normal? (being around each other, kissing, having contact?) is 72 hours enough time?

You were likely exposed before he started having symptoms. Failure to develop symptoms means you were likely already immune. However, 3 days symptom free is a good marker that he is not passing virus through saliva. It is likely still in his poop for a while, but that is not likely to be a problem.

Hand hygiene (enforced) remains critical for all members of the household in order to prevent further transmission, as it is possible that other members of the household had it, but did not develop significant symptoms, and they still may be shedding.
