Can't stop thinking

So I read these types of things all the time, but the past few days I've decided to write one. It's just going to be quick, because a handful of people know already including her... So we met Jr high, didn't think much of her but she won't leave me alone. I walk by she said hi or hello everytime, we started dating a month into school. We were together about two years then she moved out of state, staying in touch by facebook and seeing one another when she came down, another two years of that. After that I stop all communication between us hoping to get over her, I've dated four or five other people trying to get over that hill. I last talked to her Christmas brake, it was nice.... On the third day... Things, god idk, its not her; the truth of it she didn't love me anymore if she ever really did. I've now graduated high school, I still find myself thinking of her dreaming of her. I'm happy seeing her in my dreams, than I wake up, I'm ever more sad.
