What should i do???.really confused.about whats goin on in my life.?

Its sounds like this girl is just wants to mess around with you, if she ever did love you or care for you she would never have treated you this way. The best thing to do is cut her out, if she does love you she will change her ways and build a real relationship with you. If she doesnt it is her loss. Don't let someone play with your heart it isn't right you deserve much better be strong things always work themselves out.x
