I sincerely hope that in spite of the problems you face you won't give in to the temptation to end your marriage. Instead, I hope you'll do everything you possibly can to rekindle the love you once had, and even strengthen it -- with God's help.
And I believe this is possible, although to be honest, it may not be easy. Because your husband is so absorbed in his work, much of the burden to change your relationship may be on your shoulders, at least at first. But don't be discouraged; it will be worth it. Nor do you need to feel you are alone, because God loves you and wants to help you. And He will, as you turn to Christ and seek His wisdom and help.
First, make it your goal to be the best wife you can possibly be. Let your husband know you love him, and back up your words with your actions. An unhappy, tension-filled home will drive almost any spouse away. Instead, make a determined effort to avoid complaining or faultfinding, and express appreciation whenever you can. The Bible says, "Better to live in a desert than with a quarrelsome and nagging wife" (Proverbs 21:19).
Most of all, put Christ first in your life -- and your marriage. God loves you, and once you discover this great truth your life will never be the same -- and neither will your marriage. Jesus said, "My command is this: Love each other as I have loved you" (John 15:12).
