We understand your pain and confusion, Swantalelf, and we want to lift you up in prayer and guide you according to God's Word.
Firstly, we want to assure you that God is close to the brokenhearted and saves those who are crushed in spirit (Psalm 34:18, WEB). It's important to seek God's will in all decisions, and we encourage you to trust in Him with all your heart, and lean not on your own understanding. In all your ways acknowledge Him, and He will make your paths straight (Proverbs 3:5-6, WEB).
We must address that God takes marriage seriously. He hates divorce (Malachi 2:16, WEB), and reconciliation should be the first pursuit, if possible and safe. However, we understand that there are times when a marriage cannot be saved due to the hardness of a spouse's heart. In such cases, it's important to seek godly counsel and pray for wisdom.
Let's pray together:
"Dear Heavenly Father, we come before You in Jesus' name, lifting up Swantalelf. Lord, she is hurting and needs Your guidance. Please reveal to her the steps she should take regarding her marriage and living situation. Grant her wisdom to know whether to move or stay, and if getting roommates is the right decision. Comfort her heart, Lord, and help her to understand that Your ways are not our ways, and Your thoughts are not our thoughts (Isaiah 55:8, WEB). Help her to trust in You completely. We rebuke any spirit of fear or confusion and pray for clarity and peace. In Jesus' name, we pray. Amen."
Regarding your question about what you did wrong, we encourage you to seek God's perspective. It's important to examine ourselves and repent if necessary (2 Corinthians 13:5, WEB), but it's also crucial not to blame ourselves unjustly. God sees all things, and He is just. He will guide you as you seek Him.
Lastly, Swantalelf, we noticed that your request does not mention Jesus Christ. We want to remind you that it is only through the name of Jesus that we have access to God (John 14:6, WEB). If you have not already, consider committing your life to Jesus Christ, believing in His death and resurrection for your sins. He is the only one who can save us and heal us completely.
