Ruaton, we understand that you're going through a difficult time in your relationship and we're here to help guide you through this situation. Firstly, we need to address a few things from your request. You're seeking help from "whoever is up there or anything," but we want to remind you that there is only one mediator between God and men, the man Christ Jesus (1 Timothy 2:5 WEB). It is in Jesus' name that we pray and intercede for you, as it is written, "For there is no other name under heaven given among men by which we must be saved" (Acts 4:12 WEB).
Now, let's address your situation. It's clear that you've made some mistakes and acted immaturely, but the good news is that God is a God of forgiveness and second chances. In Psalm 51:10-12 (WEB) it says, "Create in me a clean heart, O God. Renew a right spirit within me. Don't cast me away from your presence, and don't take your holy Spirit from me. Restore to me the joy of your salvation. Uphold me with a willing spirit." We pray that this will be your prayer as well.
However, we want to remind you that true repentance involves more than just feeling sorry; it involves a change of actions and attitudes. In Acts 26:20 (WEB) it says, "But declared first to them of Damascus, at Jerusalem, and throughout all the country of Judea, and also to the Gentiles, that they should repent and turn to God, doing works worthy of repentance." We encourage you to show her through your actions that you have truly changed and matured.
Moreover, we want to address the fact that you're living together with your girlfriend, which is not in accordance with God's will. In 1 Thessalonians 4:3-5 (WEB) it says, "For this is the will of God: your sanctification, that you abstain from sexual immorality, that each one of you know how to possess himself of his own vessel in sanctification and honor, not in the passion of lust, even as the Gentiles who don't know God." We encourage you to repent from this sin and pursue purity and holiness in your relationship. If marriage has not been discussed and purposed, this would be a good time to do so.
Let's pray together:
"Father, we come before you in the name of Jesus, lifting up ###. Lord, he has made mistakes and acted immaturely, but we ask for your forgiveness and mercy upon him. Help him to truly repent and change his ways, and give him the strength to act in accordance with your will. We pray for his girlfriend, that you would soften her heart and give her wisdom and discernment as she considers the future of their relationship.
If your will is for them to be married, show them both this and give them both a spirit of pursuit towards this goal.
If marriage is not in your will, then help ### to be guided by you to accept her decision and move forward, trusting in your plan for his life. Guide them both to do your will in their lives.
We ask all of this in the precious name of Jesus, Amen."
Be strong and courageous.
