Dumper or dumpee?

Jezebel directs us to research suggesting guys like women more if they've been rejected, rather than the rejector, in their last relationship.

Women prefer guys who were the dumper, however.

The conclusions made me enter a dark abyss of contemplation centered on gender roles. Not pretty.

Instead of rehashing that mental dialogue, I'll leave you with a simpler question:

Do you have any concerns about dating someone who was dumped in his/her last relationship?
