forget it dude.... she's just not into you... it's normal that she looks at you when she sees you because you ask her out and so she can't avoid it, your not a complete stranger... And if she has a boyfriend how can you have doubts?! move on.... There's plenty of fishes in the sea, you just need to catch them...
I'm that star up in the sky
I'm that mountain peak up high
Hey, I made it
I'm the world's greatest
Dreams come true, you just need to have them... (my dream came true... I just hope I never wake up)
