Yes, your marriage can be saved, and I pray that you and your husband will do everything you possibly can -- with God's help -- not only to rescue it, but to make it even better.
I have often said that a good marriage actually involves three people: the husband, the wife -- and God. After all, God gave marriage to us, and He knows what it takes to make it the happy and secure relationship that He intended it to be. His original design for marriage is still valid: "It is not good for the man to be alone. I will make a helper suitable for him" (Genesis 2:18).
This is why I urge you and your husband to turn to God and submit your lives and your marriage to Him. Begin by asking Jesus Christ to come into your lives -- and then ask Him to help you work together on the problems that are destroying your relationship. Instead of trying to control each other, ask what you can do to help your spouse.
As part of this, ask God to help you see your money from His point of view. God knows that we need money -- but He also knows that we often waste it or want things we don't really need. Work together on a budget, and ask God to help you follow the Bible's mandate: "Keep your lives free from the love of money and be content with what you have" (Hebrews 13:5).
