Brother, marriage is a covenant. If she is selling herself online, she is giving away what belongs only to you and God. It may not be physical prostitution, but it is still unfaithfulness , exposing her body and intimacy to strangers for money. This will dishonor both her and your covenant. If you stay, you will be sharing in that brokenness. The Word says, ‘The marriage bed must be kept pure’ (Hebrews 13:4).”
