How Could...What Did...?

How could you do that to me; Treat me like some kind of fiend? How could I end up being used; Knowing how I felt about you? How could you rip my heart out; You know you look beautiful when you pout. What did I do to deserve this; You must know how much you'll be missed. What did you think when we first met; "He's a sad animal, I'll make him my pet?" What did you think I wanted with; Doesn't matter, you just push me around and treat me like a fool.
