I broke up with this girl because...?

why dont you ask her to hang out with you and bring up that you miss the fun times you had when you were together. if she answers positively try and make a move with her if she goes along with it then take your second chance if she does not thenshe is not interested anymore. but it does sound positive if she is sending kisses back. the only thing she can do is say no. if she does then move on. good luck.
