People do not
exist
to complete you.

Their pain is not beautiful or romantic.
Their emotions are neither shallow nor too mysterious to understand.
Yes: they might be overwhelmed, under-prepared, broken.
But stooping to pick up the pieces and fit them back together doesn't provide you with any ownership of whatever it is you've made.

And if you step back and realize that
what you've built isn't what you think it should be,
then find a way to respect them for who they are.
And do it without any preconceptions about
obligatory desire or mandatory love.
