Asking Eric: My married friend touched me and kissed my cheek — is she flirting?

Dear Eric: I am a long-retired senior citizen. I manage my days by finding things to do. In the evenings, I generally go out to a handful of local establishments. Being single I sit at the bar to dine and have a cocktail. I am friendly and chat with just about anyone

At one establishment, I run into a lady from time to time. She is married but her husband works long hours and is seldom with her. I have met him a couple times. Seems like a nice enough fellow.
