Many couples experience what you're going through, and I sincerely hope you won't let these "bumps in the road" discourage you or make you do something wrong.
You see, you and your husband made a vow before God when you were married a vow to be faithful to each other as long as you live. God loves you, and He wants you to take that vow seriously, because it will see you through the rough times and bring security to your marriage. Jesus said, "Therefore what God has joined together, let man not separate" (Mark 10:9).
Many enter marriage thinking it will be an uninterrupted romance. But marriage involves adjustment, and a willingness to forgive and to change. The biggest enemy of any marriage is selfishness insisting on our own way, and not seeking what is best for our spouse. Look carefully at the Bible's description of true love: "Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs" (1 Corinthians 13:4-5).
The most important advice I can give you, however, is to make Christ the center of your marriage. He loves you, and He wants to help you. If you and your husband have never done so, ask Christ into your lives and make Him the foundation of your relationship.
