I agree that most of our personal history is looked back upon with great emotion (both positive and negative). One can only speculate if the boy still loves you, but one could also assume that if your feelings for him are as strong as your, he most likely still holds you in a special place as you do him.
Fortunately, I am a romantic at heart; I do remember my childhood with wonderful memories. As pohnpei points out, we do tend to chose to remember only the good things. I would suggest keeping him in your memories, but not allowing him to keep you from moving on with your life.
