If you have chosen to reconcile instead of divorce and decided to pray and work toward a happy marriage, then you are on a new path. It's time to let go of the past. Stop replaying old memories and focus on the future. Picture yourselves as an old couple doing loving things for one another. Share this vision with your spouse.
There is a gap between the present and the future. Make it count! Take an interest in the things your spouse does even if you don't have a natural interest in those things. Go with him to a baseball game. Sit down on the couch and watch the show she normally watches alone. Compromise for the sake of love. This solves the common complaint "We have nothing in common."
When the opportunity to fight arises, focus on the tiny detail you do agree on. Admit you don't agree but because you love him/her, you want them to have their way. You are establishing a new normal that sets an example of love that will be returned to you in time. Don't be a doormat...but be ready yield sometimes. This solves the common complaint "We always fight."
Compliments go a long way for women. Respect goes a long way for men. Be sure you lavish this currency in your marriage. This is a purposeful expression of love that is readily accepted.
Dear Lord, You promise that "He who finds a wife finds what is good and receives favor from the LORD." in Proverbs 18:22. I pray You would open our eyes to the favor You have shown us and help us to behold the good thing we have found in our present marriages. Thank You that this promise and all Your promises are good and true for all time. In Christ's Name, Amen.
