What does the Bible say about loneliness in marriage?

"The LORD God also said, “It is not good for the man to be alone. I will make for him a suitable helper.”"

Companionship was God's idea from the start. Longing for closeness in marriage is not selfish; it reflects how you were made.

"Two are better than one, because they have a good return for their labor. For if one falls down, his companion can lift him up; but pity the one who falls without another to help him up!"

Two are meant to help each other up. If you feel like you are falling alone, that is worth saying out loud to your spouse.

"with all humility and gentleness, with patience, bearing with one another in love, and with diligence to preserve the unity of the Spirit through the bond of peace."

Humility, gentleness and patience are the slow work of keeping unity. Reconnection often starts with small, kind words.

"Therefore, as the elect of God, holy and beloved, clothe yourselves with hearts of compassion, kindness, humility, gentleness, and patience. Bear with one another and forgive any complaint you may have against someone else. Forgive as the Lord forgave you. And over all these virtues put on love, which is the bond of perfect unity."

Love binds everything together. Forgiveness and kindness are choices you can make before the feelings return.

"Turn to me and be gracious, for I am lonely and afflicted."

David prayed plainly about being lonely. You can tell God exactly how alone you feel, even inside a marriage.
