We understand that you're going through a difficult time, Kimanothal, and we're here to support you in prayer and truth according to the Word of God.
Firstly, we need to address the spiritual aspect of your request. You mentioned that you need to let go of this toxic person, but you did not mention the name of Jesus Christ. It is only by the name of Jesus that we have access to God. The Bible tells us:
For there is one God, and one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all. This was the testimony given at the proper time. (1 Timothy 2:5-6 WEB)
We encourage you to come to the knowledge of the truth of Jesus Christ. Jesus said
I am the way, the truth, and the life. No one comes to the Father except through me. (John 14:6).
Now, concerning your relationship, it is clear that it was not grounded in biblical principles. The fact that you were in a relationship with a man who is addicted to drugs and exhibits narcissistic tendencies suggests a departure from God's design for healthy, godly relationships. Here is what God expects,
Do not be deceived. Bad company corrupts good manners. (1 Corinthians 15:33 WEB)
We rebuke you in the name of Jesus that you are to avoid seeking revenge. You admitted to wanting revenge. This is not Christ-like. God expects us to do the opposite,
If it is possible, as much as it is up to you, be at peace with all men. (Romans 12:18)
After theзно reminding, we find solace and guidance:
He heals the broken in heart, and binds up their wounds. (Psalm 147:3)
Trust in Yahweh with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight. (Proverbs 3:5-6)
Let's pray together:
Dear Heavenly Father,
We come before you in the mighty name of Jesus, lifting up Kimanothal. We pray the blood of Jesus would cover her and that you would deliver her from this toxic and unhealthy relationship. God, you see the pain, the hurt, and the deterioration of her heart, mind, and body. We ask that you break every ungodly soul tie between her and this man. Deliver her from the lusts of her heart, and let her find new love in you and allow you to bring a godly spouse into her life. Heal her broken heart, Lord, and help her to let go of the past. Help her to stay focused on that. Anoint her mind, body, emotions, soul and physical being in the name of the Blood of Jesus.
Father, we also pray for this man. We pray that you deliver him from his addictions and draw him to yourself so that he can find healing and a new life in Christ. We do not pray that you would bring them back together but that your will be done in both of their lives. Finally in Jesus' name, we ask for God to delivery Kimanothal from the desire for revenge for all eternity, Amen.
