Don't get in touch with her !!! This break up is all on her terms, she breaks it of and then she decides to get back in touch with you. You take some control of the situation and don't let her mess you around. It maybe that she likes to know that your still in love with her and this makes her feel good about herself.
This girl has hurt you once before don't let her do it again
Hope i don't sound too harsh but i think you should move on
Take care xx
