The Church would suggest a married couple look to Jesus for an example of how to live and to love one another. The notion, according to Vatican II, is a merger. The ideal marriage brings together the experience and life of a human couple, and the grace of God. Let’s read:
9. Through this Sacrament the Holy Spirit brings it about that, just as Christ loved the Church and gave himself up for her,(Cf. Ephesians 5:25) Christian spouses also strive to nurture and foster their union in
- equal dignity,
- mutual giving,
- and the undivided love
that flows from the divine font of charity. In this way, uniting divine and human realities, they persevere in good times and in bad, faithful in body and mind,(Cf. Gaudium et Spes, nos. 48, 50) remaining complete strangers to any adultery and divorce.(Cf. ibid. 49)
I bulleted out three important points. What do you make of them? If these are fostered, I would imagine that adultery and divorce would indeed be completely alien.
