I think a large proportion of us have at some time been very attracted to someone, but they just don't feel the same.
I have experienced this (although we were and still are good friends) and it's both a great feeling and a bad feeling at the same time. I was fortunate to express my feelings so I know the answer, I would have hated not knowing.
Anyway I played the song below for the first time in a long, long time. It's the song I attribute to her and probably always will. I love this song to bits and it always get me a big old lump in the throat.
I would paint the stars for her.
Enjoy the song.
