you dont.

Nunc iam illa non vult;
tu, quoque, impotens, noli
Nec quae fugit sectare, nec miser vive,
Sed obstinata mente perfer, obdura.


Now she doesn't want you anymore;
you, too, should not want her,
neither chase her as she flees, nor pine in misery:
but carry on obstinately.

so nice. this latin thing. whatever it is. so sad.
