Lovesick [You tell me that you love me, then you go and leave me. Why

Dear, I wrote you a song. 
Despite the fact you did me wrong. 
And dear, I dont know 
what the [bad word] is going on with you 
but something ain't right. 

You tell me that you love me, 
then you go and leave me. 
Why you do this to me baby? 
I'm lovesick, I just can't sleep, 
just can't eat, can't do much of anything at all. 
'Cause im sick and in love with you, dear. 

And dear, I wrote you a song. 
In hopes that you would sing along. 
And dear, I've been working my [bad word] off for you 
'cause something ain't right. 

You tell me that you love me, 
then you go and leave me. 
Why you do this to me baby? 
I'm lovesick, I just can't eat, 
just can't sleep, can't do much of anything at all. 
'Cause im sick and in love with you, dear.
