Sounds like mind reading and projection from her side. I'm sure others are going to chime in here, but I wouldn't be a sure thing to her. I would have answered that with some ambiguity. The others here advocate saying " My life is already complicated why would I need another woman to make it even more complicated?" If your wife is cheating on you how do you think she would answer? Probably with have truths, ambiguity, and mystery.

Mine went away to her niece's bday in PA. I miss my son like crazy. Before they left Sat and just returned 10 minutes ago as I was leaving to GAL. She said to me "Enjoy your solitude, and try not to burn the house down." So I replied: I'll be sure to order up a couple of hookers, some cocaine and a keg. " so she replied "Just make sure that they're cute ones."
First thing she asked me upon coming home was "How were the hookers?" I said "Which ones? Monique, Unique, or Bambi?" I said that they were pretty good they even clean the place up for me. Kissed my son goodbye and went out to GAL. I miss him so bad I want to spend some time with him today but I need to get out of the house.
