I think i'm obsessed?

okay first of all I am not trolling this is serious I want to know if I am obsessed! Okay well I had this girlfriend she is and ex now we broke up a few months ago and I just started talking to her on Facebook she is 15 years old and I love talking to her after the break up a few months later we become friends for awhile then stopped talking so like I said we just started talking again and she is being such a ****** saying she had with her new boyfriend and in my opinion 15 is way to young to be having ! and I know a lot of you will agree with me! anyway even though she is being a ****** I still love her! and I cant stop telling her! I want her back! every time I say "I love you" to her she tells me to eff off and then says "well i dont love you anymore!" but I still say I love you to her and I even made a video for her witch you can watch here http://www.youtube.com/watch?v=gOZZMpAOjXE also look at the comment she left on the video it wasn't nice at all and she is being so mean to be and all I am doing is being nice to her! I think about her all the time! she says if I don't stop saying "i love you" to her and trying to get her back she is going to call the cops on me and I believe she will do that! but anyways what I really what to know is am I obsessed with her? I love looking at pictures of her on FB cause she is so pretty we were dating in school not internet dating lol! but please answer my question!
