What do i do?!!?!?!?!?

first of all calm down, its not easy when your in that situation, its also not nice what shes done to you, sometimes words are cheap and untill you put them into practice, it seems her ex is playing with her emotions and shes doing the same to you, it could also be a front shes putting on with you and your never going to know, your minds going to be all over the place, thinking things that may not be there,so my advice to you is, dont contact her, she knows were you are, and if she likes you that much she will contact you, if you havent done anything wrong then you have nothing to feel bad about, good luck.
