I would continue to DB, treating her as one would treat a roommate or a cousin who is recuperating and in your care.
I would NOT, however, recommend "The Love Dare" approach. It is very anti-DB/DR in that it is basically a textbook for "pursuing," which doesn't work. It's best utilized (if at all) but a couple who are BOTH in reconciliation, ready and willing to work on their marriage, without a third person involved.
I think you should consider exposing her affair to her mother, once your wife has recuperated, if you think she would be supportive of your marriage.
