About 10 years ago I had a short-lived, whirlwind romance with a man who was taking a long break from a complicated relationship with another woman. Once things got emotionally intimate with me, he bolted back to her and they eventually married. I was devastated. Despite my initial grief, we remain a presence in each other’s lives. Although we have transitioned to being only friends, there has always been a flirtatious quality to our interactions. I refer to him as The Question Mark because I have always had the “what if” question haunting me about him. What if he had been more available when we first started dating? What if our career paths were not so different? What would happen if we lived in the same city today, now that we are both single again?
