Theres a stone in my shoe :((?

[Wing]

Okay I really need help on this, may sound stupid but yeah here it goes:
I love this girl so much but its already over, theres nothing between us right now and has been like for 2 and a half years. So yeah I thought that I have moved on but the problem with me is I cant stop myself from viewing her Facebook/Twitter account just to check out what is she up to. And I do that for almost everyday!
Another thing is, I dont wanna get back to her I have no intention on doing that, I am now just concentrating on my studies and I hope that I will get a decent job and pay so she will know whats shes missed I just wanna show her that I have changed thats it, not getting back to her. And I am working on it. Someone please tell me what am I supposed to do? And what exactly my problem is? Best answer gets 10 points )

.For starters,if you have something to prove.Then do it for your own satisfaction.Also stop stalking this girl.Which would be the smart thing to do.That's if you don't really like her
