Est-ce que j'existe encore pour toi?

I think I did everything right...
I've got your toothbrush next to mine, and your sleepers by the bed.
I lay beside you every night, and kiss you goodnight.
I even put the red light on in the south-west corner.
I pour you tea, and I caress your hair.
And yet - you're not here.
I think I did everything right though. I don't understand.
