Stop denying your last boyfriend ended things, because it turns out straight men find women who were dumped in their last relationship more attractive than those who did the dumping. Meanwhile, it's the opposite for straight women; they lust after the male rejecters.
While researchers at the University of Michigan were surprised by findings — expecting both men and women to prefer either the dumper or dumpee — I can't say that I am. With absolutely no scientific proof, I can say that men are terrified of rejection, possibly more than women. So, of course, they're going to go for the girl without a track record of breaking hearts.
