I guarantee that this supposed "flawless" new guy won't satisfy you either. The "endless need" inside you can't be filled by another person, or even multiple other people. You need to satisfy yourself first, love yourself first, and then be honest with the people in your life. And maybe an open relationship/polyamory is perfect for you, who knows. But this attitude of "just hadn't found the right man to appreciate me" is not actually reality.
