Here is the story,
I dated this girl for a year and it was amazing, amazing, amazing. She was my first for everything and a year later after we broke up, im still not over her. She broke up with me, and i moved to uni and i am still not over her, Now I am back in the same country. Now all of a sudden, we spoke on SPAM last night and it was amazing and funny and she said she has always a soft spot for me, and she was asking me about who i got with, i sensed a little jealousy, and she even was asking me to chill and go for a run... and it was great. That was last night, and im trying to rebuild this, and i get soo oftenly carried away with her, ask about her, wait for her to get online, want to talk to her, and when i talk to her, just before she said on FACEBOOK "Youre doing that thing when you become so demanding and want to know things", and i cant help it, i want to know what she is up to and i want her. I dont know what to do, she is going out friday and and again the next day and the thought of her hooking up with another guy kills me. I dont know how I can get her so intersted in me again, because i sensed a little bit of it last night. Now i just killed it by my obssesive side getting in control, how do I win when SHE Doenst initiate contact and i want her so badly in my life, after a year i havent found a girl nearly as good as her and I am so lost. In this year of us being a part she has seen me in a bad light because she has heard of me asking about her and so on, and i dont blame her, but i cant help it.

PLEASE help me and just explain it simply for me to process
