"I'm Lonely" lyrics

When I woke it was a lovely day
Everything was going fine
I never thought that you'd run out on me
I always figured you'd be mine

I'm lonely baby and I want you back
(I said I want you back baby)
I'm lonely baby and I want you back

Now and then I get to thinking 'bout
All of the things that we used to do
It seems to me that there's no getting 'round
But all I want is you

Cause I'm lonely baby and I want you back
(I said I want you back baby)
I'm lonely baby and I want you back
(I said I want you back baby)
I'm lonely baby and I want you back
(I said I want you back baby)
I'm lonely baby and I want you back

Please baby tell me why'd you step out on me
You can't just up and leave
