I am smart but but smart girls don't indulge with me

I'm a female student and i understand the problem kind of, I usually end up talking with less attractive guys when i'm at a party because I'm shy and they are just easy to be with. They also would never hit on me btw. Sometimes it worked out for me if a nice looking guy just smiled at me, it makes me more confident to go talk to them... that's how I got my two (ex) boyfriends. ;)
