I cant go there again

Every new beginning, comes from some beginnings end.
every time you kill me, i am born again.
every time you close that door, another one is opened,
and every time you say good-bye, a different word is spoken.
every time you look at me, my back is facing you,
and every time you ask to see me, I'll have something else to do.
every time i join your game, your not playing fair,
and every time i really love you, i pretend that i don't care.
