Naruto can't handle this
Not any more
He's at his limit
Done
Can't keep holding on for sasuke
Asshole that he is
Cant because he's tired
Tired of loving someone who doesn't love him back
Tired of loving someone who tries to kill him repeatedly
Tired of chasing him, of rejection, and of crying when it's all done again getting so close just to be pushed away and nearly killed…again
Naruto is just plain tired of not being loved back
Just plain tired
So he gives up, he gives in
And because he can't change sasukes decision
He knows and accepts this
However he can't move on either
And because he can't move on either he takes the next best option
When sasuke does come back,
He expects naruto to be there
With open arms
Still loving him
But he's not
His grave sure is though
Sasuke is devastated
He didn't mean it
But it doesn't matter anymore
