What am I supposed to do?

What am I supposed to do,
Since I don't have you?
Do I sit there and smile,
When my saddness is all in a pile?
Do I move on,
Though I'm lost without you when you're gone?
Do I try to get you back,
Though courage is what I lack?

What am I supposed to do,
When I can't accept the fact that we're through?
Do I forget how we were,
Now that you're with her?
Should I try to be friends,
Though you broke a heart that doesn't mend?
Do I hide my sorrow,
And hope for a better tomorrow?

What am I supposed to do,
When I know you still love me too?
Do I tell you how I feel,
And prove my love for you is real?
Do I ignore you,
And let you do what you want to do?
Do I look at the night sky,
And start to cry?

What am I supposed to do,
When I know I was the one who was untrue?
Do I tell you my mistake,
And let you think my love was fake?
Do I tell you how I cheated,
Though you had everything I needed?
Do I sit here,
And face my worst fear?

What am I supposed to do,
When I hurt you?
Should I try to make things better,
Hoping we can still be together?
Do I blame you,
For me being untrue?
Do I tell you how you were never there,
And how all your harsh words weren't fair?

What am I supposed to do,
When I blame myself for hurting you?
Someone tell me,
What am I supposed to do?
