Are guys intimidated by smart girls?

I thought this guy really liked me before he found out how good i did in school. I was chosen as 1 out of the thousand people in my my school to compete in a geography bee and this guy i thought liked me was not. He seemed a little less interested in me after all of that happened, especially because i out lasted some of the smartest kids in the school, i did not win the contest thing but i did make it to the second to last round and am on high honor roll and 2 honor societies for my schoolwork and music. So are guys intimidated by smart girls? Oh and I also talk about this guy in another question " why wont this guy talk to me?" please and thanks in advance for all answers!!!
