Luke 16:18 Anyone who divorces his wife and marries another woman commits adultery, and he who marries a divorced woman commits adultery.

Ok, feel free to stay married to someone who don't love you if you want.

The rest of us who'd use Luke 16:18 at most for wiping our godly rear will be able to choose - free from any religious obligation coming from religions that don't interest us - what to do in such scenario.
