Women fall in love without permission. We all do it. And then we walk around all bewildered as to why he doesn't love us back. Maybe a good course of action would be to state our intentions up front. Like this:
Woman: Hello, I am about ready to unreasonably and irrevocably fall tail over tea kettle in love with you. This is your only warning.
Man: thank you for the heads up! *leaves man shaped hole in door*
Then the woman can move on without confusion. It would solve a lot of problems. Just my solution.
