What am I to you?

You are my everything
You were my light
That had the strength to guide me through
lonely nights,
You were the stars
That helped our love to come this far
You were the shadow by my side
That gave my happiness and pride
You were the ocean sand
To tell me you'd always be there
To lend a hand
You were the moon
That would tell me my fears would be
over come soon
You were the rain
To be there and ease the pain
You are to me my everything
and the joy and happiness that you'd bring
I love you - of course i do
but what i am wondering is.....
What am i to you?
