<human>: Can you succinctly summarize the text in 1-3 sentences?

This girl has been my best friend throughout all of our school life since the second grade. We decided to give dating a shot after sleeping together when we were both finally single at the same time. 
  
  We have always made plans about our future and lives together since all the way in fourth grade when we talked about sailing to Paris and living together someday. 

  We started dating right before she left for college over a year ago and since she had an incredibly difficult time adjusting from small town life to a UC, I spent a lot of time and energy on focusing on her happiness and making sure she felt better. This year when she left for college, she says she doesn't have the time for me and it's for the best that we break up. 

 I have built up and romanticized my feelings for her since the fourth grade and have always thought of spending my life with her and we have always been here for each other to talk to. Now I haven't talked to her in a week and am trying to move on by focusing on myself and doing all of the right things post-breakup, but I don't want to lose her. I want her to be happy, but at the same time I want her to be happy with me.
<bot>: fell in love with a girl, then she leaves me for feeling like she won't have the attention for me, even though I spent countless hours her first year away talking to her on the phone to help her be happy with herself.
