WHO knew

I wasted all my time, I wasted all my nights
I wasted it on someone who's indifferent
He didn't love me right, you told me I was blind
But I never really wanted to listen
You have been here since day one
Seen my ups and downs (My ups and downs)
Never left my side once
Yeah, you stuck around
Who knew, it was you?
You have been here all along, you have always been the one
Yeah, who knew, it was you?
You have always been the one and that's the truth
You have been here all along
I never saw the signs, he didn't treat me right
But I just couldn't let him go
You waited patently, you waited for me
And you showed me what it was to love
You have been here since day one
Seen my ups and downs (My ups and downs)
Never left my side once
Yeah, you stuck around
Who knew, it was you?
You have been here all along, you have always been the one
Yeah, who knew, it was you?
You have always been the one and that's the truth
You have been here all along
You have been here all along
You have been here since day one, ah-ee-ay
Never left my side once, ah-ee-ay
You have been here all along
Who knew, it was you?
You have been here all along, you have always been the one
Yeah, who knew, it was you?
You have always been the one and that's the truth
