What is up with this girl?

ok, im no relationship guru. and i, myself am going through a rough time with my man so im gonna just tell u my opinion. sounds to me like some mixed singles are going on. you obviously like her since you asked her out the following day. and as for her, i'd give it a bit more time. its not like she lied just to get out of a date so wait & see what happens. if she wants you, she'll be knocking on your door for sure.
