If you approach her that way she will definitely not go out with you.Need advice on asking a girl out?
Be straight forward (but nice) i really like you do you fancy going out with me sometime
you could try that. just don't be so awkward when you ask her and if she says she doesn't want to go out, don't say something like ';haha, i was only joking!';
well tell her how you fell about her tell her that you like her and then ask her out
