>"she'll probably fall easier for you if you treat her like she's someone you'd want to have sex with rather than have as a girlfriend."
NO! You need to show something like sex is NOT what your only interested in. Showing or especially TREATING someone only like you want to have sex with them is NOT the way to go. That will probably piss her off. You need to remain as friendly as possible but not too much. Find out some of her interests if you can, and if possible show your into them too. Before considering a relationship, you should work on getting her to know you, and think very positively of you. However, I do agree with 610 about complimenting her, but not overly, and not in a super way that immediately gives it away that you like her, because coming off too quickly like that most of the time may potentially cause game over. ;-;
Do you know at all if she shows any signs of liking you? o.o
