Tell me who did the pledge of love please comment

I've made a vow to no one but you
I pledge my love to forever be true
I'll take care of you and treat you right
I'll lay beside you all through the night
I'll feed you and clothe you and keep you warm
I'll hug you and kiss and give you shelter in the storm
I'll help you and guide you and clear a path
I'll protect you and shield you from angry man wrath
I'll Ill listen to your problems help you solve them too
I'll make you a rainbow and let the sunshine through
I'll take your side even if your wrong
Just to prove are love is strong
I'll plant you flowers and make them grow
They'll be a symbol of of love that only we'll know
I'll whisper your name when know one is near
So low that only you can hear
you'll feel my love even if we're apart
You'll know that we are one in heart
