In my book, Hope for the Separated, I’m bold to suggest that you should be kind to the spouse who has walked out on you. I know it doesn’t seem natural, but we are called to love our enemies, and love is kind. The word ‘kind’ means ‘to be useful or beneficial’. What can you say or do that would be useful or beneficial to your spouse?
If you are a husband who has left, there are scores of things around the house that you could do for your wife, if she is willing. If your wife has left you, you may still be able to do some things that are ‘beneficial’ to her. What is to be gained by not helping her? You can be God’s agent of love. Love, expressed in kindness, is often the first step toward reconciliation.
