Please help with this girl puzzle:)?

Well if you think she might like you then say something sweet but FIRST make sure she does NOT HAVE A BOYFRIEND!!! What a jerk you would be if she did and you flirted anyways. You should say ive noticed you a few times and i think your really pretty and if her reaction is like uhhh thankss.. then be like but i mean just in a friend way but if its like awhh thanks i think yu are to(; or something get more personal i guess start playing 20 questions and ask her things like what her hobbies are then come to the question do you think you might like me..? lol
