Nice guys finish last

Ok just finished abother 3 mile run, I have to admit i did not experience as much pain today on this run, I do feel a little better, but am still in one of my dark moods. What is it with females? They always complain about not being able to find a decent guy, but yet as soon as they find one all they want to do is push you to the limit, and find something wrong, then break your heart. I guess its true what thet say, nice guys do finish last.
