Cosmopolitan magazine are looking for women who have dumped a guy only to realise afterwards that it was completely the wrong decision. We want details of what lead you to dump him. Perhaps you thought the grass was greener or you missed your carefree single days? We'd also like to know how he reacted to the breakup and the moment you realised it was the wrong decision.

Perhaps you'd been too hasty and wish now that you'd voiced your concerns and tried to work on the problems before bailing. We also want to know if the guy was willing to take you back after you realised your mistake.
