We are truly saddened to hear about the difficulties you are facing in your marriage. Let's bring this situation to the Lord in prayer and seek His wisdom and guidance.
Firstly, it's crucial to acknowledge that God's design for marriage is a lifelong commitment between a man and a woman, reflecting the union between Christ and His church (Ephesians 5:22-33 WEB). The issues you're facing, including the constant interference from your husband's ex-wife and the sharing of intimate details, are not aligned with biblical principles.
In the Bible marriage is taken very seriously. For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh. (Genesis 2:24 WEB).
Let's address the issues you've raised. Your husband's behavior in sharing intimate details about your marriage with his ex-wife is a breach of trust and not aligned with biblical principles. The Bible teaches us to be faithful and honor our spouses (Hebrews 13:4 WEB).
Your husband is being gaslighted by his ex-wife's lies, which is not something to be ignored. And let us consider how to stir up one another to love and good works, not forsaking our own assembling together, as the custom of some is, but exhorting one another, and so much the more as you see the Day approaching. Hebrews 10:24-25.
The fact that your husband's ex-wife is interfering in your marriage and causing discord is something that needs to be addressed firmly but lovingly. This is not pleasing to God, and it's important for your husband to set boundaries to protect your marriage.
Regarding the accusations of narcissism, it's encouraging that your therapist has assured you that this is not the case. Remember, the Lord knows your heart, and He sees the truth. Trust in the Lord with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight. Proverbs 3:5-6 WEB).
Now, let's pray together:
Dear Heavenly Father,
We come before You, lifting up this sister in Christ who is facing tremendous challenges in her marriage. Lord, we ask for Your divine intervention. Please help her husband to see the truth and set boundaries with his ex-wife. Help him to understand the sacredness of marriage and the importance of honoring and cherishing his wife.
Lord, we pray for wisdom and discernment for this sister. Guide her steps and give her the strength to handle this situation in a way that honors You. Help her to trust in You completely, knowing that You are faithful and just.
We also pray for healing in their marriage. Lord, restore the trust that has been broken, and help them to rebuild their relationship on the solid foundation of Your Word.
In Jesus' name, we pray. Amen.
Remember, God is faithful, and He will not leave you nor forsake you (Deuteronomy 31:6 WEB). Trust in Him, and He will guide you through this difficult time. Do not be afraid to discuss the issues with your husband. Do not be afraid to seek a counselor who will help the marriage with the help of God.
