"Don't cry because it's over, smile because it happened"

Please give back me my K.
I miss him so bad. I thought that if I got hurt by some reason, he would care me. Sadly, he doesn't.
I cannot breathe well. I feel like something blocks my throat...again.
Why doesn't it disengage me?
Maybe I should leave him because he will waste his life if he chooses to be with me.
And maybe I don't have to worry because it never happens.
How can he love me?
