Ever had a date that talked all evening about being in love with someone who is definitely not you?

I've had two such dates. In both cases the guy talked for hours about an incredibly beautiful, insanely rich, super talented, empathetic, wise and saintly woman who had won his heart but, due to her circumstances as part of an immensely powerful super rich family, she was unable to marry him. Each time, I wondered about why they went out with me (in both cases they already knew me for years as a friend) and then spent the entire time talking about a woman they were hopelessly in love with, a woman so incredible it was obvious no other woman could ever compete. If they were trying to scare me away from any ideas of romancing them...all I can say is...it worked. I have not seen either one since. One of them would have been of interest to me (he was a long time family friend) but I erased the idea from my mind and haven't seen him in years now.
