Why Do You Have to Break My Heart Again?

Why do you have to break my heart again?
Why do you have to say goodbye at the end?
Suddenly he's leaving town again
I was doing fine, oh I could pretend

Happens all the time
Just when I think he's mine
And things are going fine
Oh no

Why do you have to break my heart again?
Why do you have to say those things to me?
Just when I thought that I was moving on
Boy you just had to come along
