To someone I loved

I want you to know the pain you put me through, I know we had problems but they were nothing we couldn't have worked through, you left me lonely like we never loved at all, I couldn't tell you how many times i just waited by the phone hoping you'd call, it broke my heart to watch you slip through my hands, and how you could love me so much but move on so quickly i guess I'll never understand, but soon you'll see that you made a mistake, and everything quite didn't turn out like it was supposed to be, and one day you'll be missing something deep in your heart, something that truly loved you, that something is me.
