Don't...

Don't mess me around
When you know I care
Don't break my heart
And promise to be there
Don't catch me when I fall
If your gonna tease me
Don't play with my heart
If you didn't want us to be
Don't get angry with me
When you see I moved on
Don't toss me aside
When you said we Don't belong
Don't mess with my heart
When you know how it hurts
How could you lead me on
If you didn't think we'd work
