She wasn’t sad. Just numb.
It’s not that she could not sense his love. She just didn’t know what to do with it. And it’s not that she did not want to love, she just didn’t know how to anymore.
Because the truth is, after a while, you just stop feeling anything at all. After you’ve given so much of yourself away to people who didn’t deserve it, you’re not left with anything to give. You don’t know what to feel anymore. All you feel is nothing.
