Butch in need of help- So there's this girl right...?

I was kinda friends w/ and liked her in Freshman year and our friendship kinda faded away a little I guess it's because I never had any cles w/ her in sophmore year and she's w/ her friends and I'm w/ mine....and now in junior year I have her in one of my cles again... so I still like this girl but I can't come up w/ a conversation I guess it's because I'm pretty shy and we haven't talked in awhile... oh yeh she sits right next to me in cl so I'm just like I don't no what to say to her... so umm... help? and one more thing I don't no wheter or not she's a , bi. or straight.... Bcuz on her myspace profile it says no answer for her ual orientation...
