I feel a separation coming on...

I've been diagnosed with heartbreak
and baby you've got the cure
but sometimes I sit and wonder how much I can endure
cause boo I'd give you all of me
but were we really meant to be?
Becuase suddenly this love has become like a chore,
when it used to mean so much more.
What happened to the days when I knew your heart was mine?
Now I'm fighting for just a minute of your time.
Tell me how we can go back to smiling, holding hands, and laughing
cause now it's all cursing, slamming doors, and crying
Can't you tell this love is dying?
