Not only for a while

You are my heat when it's cold,
A shoulder to cry on when I'm old,
You fill each day with hope and joy,
I never want to say goodbye,
We will dance through the storms and glow with warm thoughts in the sun
There will be tears through the years,
But with you by my side I shall have no fears,
I hope I fill your soul with the endless love you have given me,
This love is for eternity
Not only for a while.
