After I was divorced and middle-aged and back in the dating pool, I unfortunately had to kiss a few more frogs. One I recall was a tongue-darter -- very disconcerting and unromantic. And another one was worse, he had bad breath and tasted like a dried-out steak every time I kissed him. Beef is okay to eat, but NEVER to kiss.
The bottom line is that rejections are a fact of life -- we all experience them and we all hurt when we do. The best thing we can do is to soothe our emotional pain, take steps to revive our self-esteem, and to connect to our core groups and by doing so remind ourselves that others value and love us even if our date does not.
