Do you ever feel a profound relief when your crush isn't around?

I have very deep feelings for a friend of mine. When she's around (in town I guess) I always wait for her to call, I don't make plans in hopes she'll invite me somewhere, etc. When she goes on vacation or away for the weekend or anything like that, it's like a weight is lifted from my shoulders because I'm no longer climbing the walls HOPING she'll just contact me. How odd is that? Has anyone else experienced this kind of contradictory behavior? Thanks!
