If a person seeks a divorce because "they fell out of love”, the person who “fell out of love” never knew or understood love.

The NT Bible uses differents words to describe love. One of the words is 'phileo' and is often translated as 'brotherly love' – you can think of this as emotional attachments and goodwill towards other people. Another word is 'agape', which means an 'unconditional love' provided to others. When a person commits their life to another, to love them till death, this bond is not a commitment of goodwill as long as the “connection” lasts. The commitment is an active and willful pledge to meet the other person's needs and desires until one of them dies.

Even if one of the partners checks out of a marriage, a person who loves is not self-seeking; they willfully love their mate regardless. They put their mate's well-being and happiness in front of their own. A person seeking their own happiness by wanting to “fall in love again” is just love of self. To say a spouse “fell out of love” is to minimize love.

Men have a special call in marriage as well. Men are commanded by God to love their wife just as Christ loved the church (Eph 5:25). If a man's marriage is so bad that it is killing him, he is simply called to love his wife until it does.

Be encouraged.
