First dance

I was 15 i think and i had this big crash on this girl since 10 years old.Our first dance was on her birthday party after everyone else left.We dance on that song and after that we were just looking at each other.Then i left.I was sick about her until i was 18, when i finally told her what i felt and of course she rejected me.That's alright i learned a lot of things through this experience.I FELT a lot of things.Here i am now, 4 years later in the same city as her but i havent seen her for 2 years i think...I'm with another girl and i'm very happy but memories are memories and they should stay there.Right?
