A married friend confided that she had an affair with a colleague. They had full contact and pleasured each other sexually - completely, but short of intercourse. She now feels very bad about it and has left that workplace, as well as terminated the relationship. Her husband has no idea that anything was amiss. She wonders about the following: Is she obligated to inform him? Is she considered an adulteress? What is the status of her marriage? What can she do for teshuva?
