Girls: I need your advice on a silly thing?

[smallhoney541]

Perhaps you should know she's stared at me several times (she doesn't seem attached to anyone, really) and we already talked once (which was very pleasant), but we don't share any classes (we go to the same Uni).
Oh, and once I saw her and I winked at her, and she waved right back at me.
Is it OK to tell her something like
"Hey, I don't want to talk to you only if we bump into each other. How can I find you on Facebook?".
Or would be too weird?
See, since she doesn't seem attached to anyone (shy or introverted?) I don't want to be too pushy (sending a FB invitation without telling her) or too weird (asking her if she's on FB?).
Also, how about the part about me not wanting to talk to her just when we run into each other? Is that too direct?
Thanks! (Oh, yes, I am so clueless).

Don't ask that. Ask her out on a date or to get a couple of drinks. Then she will give you her phone number assuming she will say yes. (I think she will too by the way you described her body language). Go for it!

If u see her again, greet her. say hi and approach her (this action makes us girls happy). talk then ask if u could have her fb so u can add her. she seems friendly tho ^^
