Why can't i get a guy?

Okay, so here's a question I've asked myself A LOT lately...why don't I have a boyfriend? I mean I don't understand, Guys always say "ugh i have girls that flirt with every guy" then they go out with a girl EXACTLY like that. Like HELLO?! i'm here too. I'm thinking a lot of girls out there feel the same way, am i right? well if i'm not, and all you girls out there have boyfriends I would like to take a moment and applaud you- way to be. You have a guy who cares a lot about you. I hope you're treating him well too- which i'm sure you are. But anway if any of you have tips or anything thatd be great. Maybe i'm just weird or have an aura that turns guys away. A few have liked me, but I haven't like them back. Maybe ill be like susan boyel- but hopefully not (i mean shes a great person and singer, but she has never dated or anything). I think i'm one of those girls whose friends with guys, but they only veiw her has a friend. Oh well right? As the saying goes "keep calm and move on".
