If you don’t love him/her anymore

1 Thessalonians 3:12
And may the Lord make your love for one another grow and overflow…

If you don’t love him, you can learn to love him. In fact, you must learn to love him. Remember, this kind of love is not primarily an emotion, though emotions will be involved. It’s a love you can fuel, you can cultivate, you can develop. As you start to choose to do loving actions toward him, you’ll find that your heart will follow.

Don’t give up if it seems like you no longer love your spouse.  If we make a conscious decision, we can learn to love our spouses again.  Don’t allow your love to grow cold for each other.  Rather purposefully choose to romance and pursue one another like you did when you just fell in love.
