I don't think there's such a thing as love at first sight. But probably that's for a separate thread. Anyway, how long have you known her and how many times have you actually gone out together? How well do you know her? I don't think you should throw yourself in too soon, but only you'd know if you are ready i.e. you know her well enough to make a decision and you don't think you are rushing things so much that she would definitely reject you cos you scared her.
