At some point you will realize that you have
done too much for someone, that the only
next possible step to do is to stop.
Leave them alone.
Walk away.
It's not like you're giving up, and it's not
like you shouldn't try.
It's just that you have to draw the line
of determination from desperation.
What is truly yours will eventually be yours,
and what is not, no matter how hard
you try, will never be.
