1 Peter 3:7
Likewise, husbands, live with your wives in an understanding way, showing honor to the woman as the weaker vessel, since they are heirs with you of the grace of life, so that your prayers may not be hindered.
Understand your wife DO NOT compare her to other relationships like mom, past girlfriend etc. That means ask her questions, listen to answer,and take action.
Do not impose your insecurities on the a situation. Give them to the Lord so you can react to thing with a sound mind. You have to own your insecurities and exposed them to your wife.
Be the first to reconcile. THIS TAKES HOLY GHOST POWER!!!
