To what extent is Ibn al-Qayyim's statement true that sin corrupts love and engenders enmity, taking into account the continuation of relationships between lovers despite their sin?

Gathering for acts of disobedience leads to enmity and hatred in this world and the Hereafter. Love between those who share in disobedience often turns into enmity if they do not repent. It may remain in this world, but it will transform in the Hereafter. This love persists in this world as long as desires and lusts are fulfilled, but it vanishes and turns into hatred and enmity as soon as they cease. Everyone who cooperates in falsehood will find their affection transformed into hatred and enmity.
