Ok so I had to go to another city for an event and have been fooling around a bit. On day 2 I was hanging out with this girl I met in the stalls and we hit it off. Later at night we were at a bar getting flirty and sometime there a friend of my wife, who was also visiting the same event, saw me there with her.

Now as far as I know she hasn't told her yet. But what am I to do if she has? My wife is going to be waiting for me there and while I don't intend to lie, what is the best way to maintain frame when facing a barrage of questions about our relationship?

Please help me out as I have no idea how to handle this.
