WHY ! I miss my ex boyfriend?

So me and my ex boyfriend broke up about 2 a half weeks ago. We were together for about a year. We broke up becuase I felt like it wasnt going anywhere and mostly because I wanted more attention in the relationship. I did the breaking up, and now I regret it so much. I’ve come to realize that you dont know how much you have until its gone. I want him back so badly now, yet I dont want to be the one that texts him and tells him, because I dont want him thinking im so into him and thinking I would do whatever to get back with him, becuase he can be like that. I go to school with his best friend, and it drives me crazy seeing him because he reminds me so much of my ex, by the way he talks, the way he dresses and even his personality. I dont go one day not thinking about him , and how we could of been if this didnt happen. I even always dream about him and wish every text that I get is from him, but it never is anymore. I want him back so bad, just becuase he made me so happy and was something I look forward to everyday. I deleted his number of my phonebook, but that doesnt ignore the fact that I have saved messages from him, so I still have his number. I look thru his a social site (not to sound creepy) about once a week , to see if anythings new (mostly relationship stat) but theres nothing interesting.. he also never added me on a social site when we were dating, I got upset, but I didnt let those little things get in the way. hes perfect for me and I wish he was back into my life. he told me like 3 weeks before we broke up that he loved me and he would do anything to make me happy. now I wonder if that was only all talk. do you think theres a way of getting back together? I cant go a day like this anymore, it makes me so sad =[
