(I Dont Know Why) But I Do

I dont know why I love you but I do
I dont know why I cry so but I do
I only know Im lonely and that I want you only
I dont know why I love you but I do
I cant sleep nights because I feel so restless
I dont know what to do, I feel so helpless
And since youve been away, I cry both night and day
I dont know why I love you but I do
My days have been so lonely
My nights have been so blue
I dont know how I spend it but I do
Each night I sit alone and tell myself
That I will fall in love with someone else
I guess Im wasting time but Ive got to clear my mind
I dont know why I love you but I do
