We are deeply saddened to hear about the pain and suffering you've been experiencing in your relationship. Firstly, let us assure you that God is not deaf to your prayers, nor is He angry with you. As it is written in 2 Peter 3:9, "The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should come to repentance."
However, we must address the nature of your relationship. The Bible teaches us about the sanctity of marriage and the principles of a God-honoring relationship. In 1 Corinthians 6:9-10, it is clearly stated, "Don't you know that the unrighteous will not inherit the Kingdom of God? Don't be deceived. Neither the sexually immoral, nor idolaters, nor adulterers, nor male prostitutes, nor homosexuals, nor thieves, nor covetous, nor drunkards, nor slanderers, nor extortioners, will inherit the Kingdom of God." By staying in a relationship where infidelity and disrespect are present, you are accepting and enabling sin.
Moreover, the Bible encourages us to flee from sexual immorality (1 Corinthians 6:18) and to resist the devil (James 4:7). Staying in a relationship where sin is prevalent is not God's will for you. You deserve to be treated with love and respect, as God intended.
Let us pray together:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up our sister who has been suffering in a narcissistic relationship. Lord, we ask for Your divine intervention. Give her the strength and courage to leave this toxic relationship and start anew. Help her to see herself as You see her - fearfully and wonderfully made (Psalm 139:14). Restore her self-esteem and heal her from the wounds of her past. Open her eyes to the truth of Your word and lead her to a relationship that honors and glorifies You. In Jesus' name, we pray. Amen."
Remember, God loves you unconditionally and wants the best for you. Trust in Him, and He will guide your path (Proverbs 3:5-6). Lastly, ensure that your prayers are directed to God through Jesus Christ, as it is only through Him that we have access to God (John 14:6). If you haven't already, accept Jesus Christ as your Lord and Savior, and you will be saved (Romans 10:9-10). Stay strong in the Lord, and He will never forsake you.
