But I Do

I don't know why I love you, but I do
I don't know why I cry so, but I do
I only know, I'm lonely and that I want you only
I don't know why I love you, but I do

I can't sleep nights, because I feel so restless
I don't know what to do, I feel so helpless
And since you've been away, I cry both night and day
I don't know why I love you, but I do

My days have been so lonely
My nights have been so blue
I don't know how I manage, but I do

Each night, I sit alone and tell myself
That I will fall in love with someone else
I guess, I'm wastin' time but I've got to clear my mind
I don't know why I love you, but I do
