One can place the importance or value of one relationship over another relationship without placing the value of individual persons or individual life over another.
One can place the importance of one relationship at a higher level, while placing more energy and time on other relationships.
One can feel their marriage relationship has a higher importance than their relationship with their children. Yet, see the value of each person - the spouse and individual children as equal value of life, of persons.
More energy and time may need to be expended to take care of a child or children, than energy and time needed with the spouse. Yet, the person may feel their relationship with their spouse is at a higher level than with their child.
The parent - child relationship ebbs and flows - depending on the age and needs of the child. The infant becomes a child, a teen, an adult - the parent is no longer essential to the relationship for emotional or physical needs of their offspring.
The parent’s heart may even break more with the death of a child than with the death of a spouse. Yet, the relationship of the spouses may have felt to them to be next after God.
A parent can raise children alone, but the design is for husband and wife to raise the children within the Sacrament of Marriage. The “ideal” setting is within Marriage.
In the book of Genesis, God sees something that is not good.
Gen 2:18
The LORD God said: “It is not good for the man to be alone. I will make a suitable partner for him.”
Gen. 2:21-24
So the LORD God cast a deep sleep on the man, and while he was asleep, he took out one of his ribs and closed up its place with flesh.
The LORD God then built up into a woman the rib that he had taken from the man. When he brought her to the man, the man said: “This one, at last, is bone of my bones and flesh of my flesh; This one shall be called ‘woman,’ for out of ‘her man’ this one has been taken.”
That is why a man leaves his father and mother and clings to his wife, and the two of them become one body.

Each person looks at their own life and determines what areas of their lives they place first, etc. That is their own feelings, emotions, and thoughts. Each person feels what they feel, which is neither right nor wrong - but their true emotions for that moment. They don’t have a need to prove to anyone why they feel as they do, they can explain if they wish, but they should not deny to their self true feelings or emotion. They can also change how they feel, their emotions and their thoughts based on changes in their lives.
A spouse who places their spouse after God and before other relationships, can do so without being selfish. This relationship can be the most important to them and one of the hardest to maintain.
Here is a quote on the importance of Marriage on Family Life through
World Wide Marriage Encounter.
Family Life
The relationship between husband and wife is the foundation of the family. When a couple shares greater love, joy, intimacy, understanding, spirituality and communications, the children are the first to notice and feel the affect.
Our children are the seeds and our Sacraments of Matrimony are the soil they fall on. By nurturing and cultivating our Sacraments we provide rich soil for our children to grow, flourish, and blossom in.
