Yeah I had one in high school :)

We had such a deep love for each other that is was higher then any kind of romantic love or any other kind of love I've ever experienced.

There was never any jealousy when we dated other people it was the most bizarre thing. We could sit there and hold hands or quick kiss on the lips.. even if we were dating other people.. and it didn't have any meaning or effect on our other relationships. It was like above any other relationship.

I don't really know how else to describe it but I know exactly what you mean
