Guy/dating problems? attracting guys?

[Lucy]

soo, I haven't been on a date with a guy for THREE years (since my last boyfriend) and i'm an 18 year old girl!
it's weird because many guys tell my friends they think i'm hot/fit but never talk to me after!
also, a few new guys who I see at parties (who I have mutual friends with) ask about me to my friends and add me on Facebook but it never seems to go further :/
and it sucks, i feel like i haven't had a 'connection' with any guy since my last two boyfriends (my last two BFs pretty much broke my heart) but I'm over it now and just want to have a new boyfriend

yeah i sound desperate but I want to feel loved and love someone but WHERE is the guy! and what should i do?
