my wife and I talk about this all the time in the context of our single friends. Committing to a partner definitely creates freedom. Freedom to take risks that you couldn't take with someone who might leave you at a small inconvenience, freedom to be honest with each other, freedom to let your guard down and be vulnerable, and on and on.

In English "freedom" is maybe too blunt a word. I'm sure there are nuances here that other languages may have the words for.
