Not all guys are jerks and not all girls are perfect little angels. Sometimes it's the girl that breaks the boy's heart, it's the girl that plays him, it's the girl that is talking to more than one guy at a time, and it's the girl who is only using him to get over her last break-up. So quit being such hypocrites and understand that sometimes it's us who are being the jerks.
Sincerely, a girl who realizes that both genders can be douche bags.
