What is the ruling on a relationship between a young man and a young woman via the Internet, in which they exchanged words of love and gifts, knowing that the young woman is engaged and her wedding date is approaching?

This relationship and communication over the internet is a sin, an iniquity, and an opening for the devil, because it involves following the devil's footsteps which command indecency and evil, inciting lust and falling into immorality. The fornication of the eyes is gazing, the fornication of the ears is listening, the fornication of the tongue is speaking, the fornication of the hand is striking, the fornication of the foot is stepping, and the heart yearns and desires. This relationship must be severed, the email address changed, and her email removed.
