You certainly haven't given much to go on in the way of specifics, but my advice to any concerned wife;
Understand the true principles that Jesus taught. Let your water be as wine. Take joy and create delight in doing the simple needs of living; things like cleaning, washing, bathing, going to work (these days), and everything else that is truly required of you all with a smile and a surrender to the harmony of union. Worry nothing of what shall come beyond what you can clearly see. Have faith, for you cannot go unseen. But if you worry, then you will bring shadows, darkness, and deception into your life. You will succumb to belief in exaggerations and false perceptions. Cling to the persistence and insistence of surrendering to what will be with joy in heart at all times. Know that you gave to the world a little more love than it would have had without you.
As a wife, you have made a covenant with a man to belong to him in every way. Honor your covenant and let it be sacred in not even considering challenging it or letting it become a lower priority. Restore yourself in surrender to the pure love deepest in your heart without judgment, but an honest willingness to endure and forgive all things.
If you see your husband as un-Godly in his behavior, then do as all women do, persuade from within. A wife cannot help her lost husband from a distance. As estranged, she is of no help at all and lives in betrayal of love. Be his even if he isn't as he should be in your eyes. Focus on the good that drew you to him and let any bad you perceive go. A man cannot correct himself if others are always trying to insist on what is right and what isn't.
Stop trying to live for yourself, let him live for you. When you try to defend yourself, you prevent the inspiration for him to defend you and feel his reasons why he should. If his heart is asleep, then sleep with his heart and let God wake him up and let him wake you up. Betray love, and you betray yourself all mankind.
Without more detail, that's about all I can say.
God blesses those who bless man. Be a blessing to at least one of the many especially when they are in true need.
