Theres this girl I'm friends with and let me tell you, this girl is sexy, a definite 9. She sits next to me in class and everyday she walks with me to her next class. Problem is, she has a boyfriend.I'm kind of unsure as to weather this girl is attracted to me or not. She isn't showing IOIs like hair touching or arm rubbing, but she always laughs at my jokes and smiles at me. I'm afraid that she just views me as a friend and will not be receptive to my efforts. Its really getting me down too because I haven't escalated at all and this is slowly turning into a huge friendzone. I haven't even asked for her number in fear that she'll immediately know whats up and will immediately reject me. What should I do to turn this around?

Well...take it from me....if a girl is spending time with you...shes generally interested in you to some extent....to what extent is unknown until she realizes that you're not taking things further. You're just walking and talking to her, just like one of her girlfriends do. You're not touching her at all...you're not planting ideas in her mind..ya know..You wana touch her some. And you want to make her think about you and her together.. she may have a boyfriend...but for all you know shes looking for a new boyfriend so she can dump her old one....and so far, you're not fitting the bill because she thinks you're not interested..Dont be afraid of anything. The worst that can possibly happen is she says "i'm sorry, i have a boyfriend"....big fucking deal...you can respond with "oh i wasn't aware that meant you can't have friends.."
or something like that...ya know...dont be afraid of anything. shes 1 girl out of thousands at your school
