Watching his back fading in a distance

It's hard to let go of him...
when i know that he's the one i've been waiting my whole life. 
It's hard to let go of him...
when i know that he's an answered prayer.
It's hard to let go of him...
when i know that he's my soulmate.
It's hard to let go of him...
when i know that he is everything that i want.
It's hard to let go of him...
when i know that he is everything that i'll ever need.
It's hard to let go of him...
when i know that i'll be missing him every single day of my life.
It's hard to let go of him...
when i know he's never mine to keep.
