chase her own tail 

Convincing a woman who is too good for you that she is not good enough for you. Making her jump through hoops when she has better offers on the table.

I plan to tell her to come over and talk to me some time if she is interested. She will chase her own tail for 20 minutes before some rich guy might send her a couple of martinis.
