What does Deuteronomy 21:14 mean?

But if you end up not wanting her, you have to let her go wherever she wants. You can’t sell her or treat her like property, because you’ve already humbled her. Deuteronomy 21:14 - Modern Text Bible

(If the man changes his mind, he must let her go free. He can’t treat her as a slave or commodity, since she’s already been through a vulnerable situation.)
