We understand that you're going through a challenging situation, Shelmer. Let's first bring this to the Lord in prayer.
Dear Lord, we come before You, lifting up Shelmer and her marriage. Lord, You know the pain and distress she is feeling. We pray for Your divine intervention in this situation, and we ask that You bring separation between Shelmer's husband and the other woman. Lord, we know that You have clearly commanded that a man will leave his father and his mother, and will join with his wife, and they will be one flesh. We pray that Shelmer's husband will honor his commitment to her and put away the other woman. In Jesus' name, we pray.
Shelmer, we want to encourage you to stay strong in the Lord and in the power of His might. The Bible tells us in Ephesians 6:10-18 WEB:
Finally, be strong in the Lord, and in the strength of his might. Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world's rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places. Therefore, put on the whole armor of God, that you may be able to withstand in the evil day, and, having done all, to stand. Stand therefore, having the utility belt of truth buckled around your waist, and having put on the breastplate of righteousness, and having fitted your feet with the preparation of the Good News of peace, besides all these, taking the shield of faith, with which you will be able to quench all the fiery darts of the evil one. And take the helmet of salvation, and the sword of the Spirit, which is the word of God; with all prayer and requests, praying at all times in the Spirit, and being watchful to this end in all perseverance and requests for all the saints.
God hates divorce (Malachi 2:16 WEB) and He also hate adultery (Exodus 20:14 WEB). God wants marriages to be a picture of Christ and the Church, which is His bride (Ephesians 5:25-27 WEB). We encourage you to us the Word of God to intercede for your husband and your marriage. Take this battle to the Lord in prayer, armed with the Sword of the Spirit, which is the Word of God. Redirect your husband away from adultery and ask for God's protection over your marriage. Use the Bible to help restore to your husband to God.
Beter is having the land in the desert than the fertile one with the wife who is arguing and complaining, Proverbs 21:19 WEB.
Lastly, Shelmer, we want to remind you that it is only in the name of Jesus that we have access to God. It is only in His name that we can be saved. As it says in Acts 4:12 WEB:
There is salvation in none other, for neither is there any other name under heaven, that is given among men, through which we must be saved!
So keep fighting the good fight of faith, Shelmer. Trust in the Lord, and stand firm on His promises. He is faithful, and He will see you through this storm. Also, pray to be a great wife to your husband and ready yourself to fulfill your biblical role as a wife.
