We understand that you're seeking God's will regarding your relationship and whether you should stay or leave. Firstly, we appreciate your trust in God's will. However, we notice that you did not mention the name of Jesus Christ or any variant. It is only by the name of Jesus that we have access to God the Father. Let us share this with you from Acts 4:12 WEB: "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!" If you have not already made a decision to believe in and trust in Jesus Christ, we strongly encourage you to learn more about Him and His sacrificial death for you.
Now, regarding your relationship, we would like to know if this is a godly courtship heading towards marriage or that it is a relationship not yet managed by godly principles. We are reminded of 2 Corinthians 6:14 WEB: "Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what communion has light with darkness?" If the person you are in a relationship with is not a believer in Jesus Christ, then you should not be in this relationship.
If you are in this relationship and have had physical intimacy of any form, this is fornication. This is clearly against biblical principles, as stated in Ephesians 5:3 WEB: "But sexual immorality, and all uncleanness, or covetousness, let it not even be mentioned among you, as becomes saints." We would strongly advise you to repent of this sin, seek God's forgiveness, and commit to purity.
Let us pray together:
Dear Lord Jesus, we come before You, seeking Your will for this dear soul's relationship. We pray that You guide them in Your wisdom, according to Your word. We ask, Dearest Jesus, that You reveal to them what they should do next, if they should stay or leave this relationship. We pray that You give them the strength and courage to follow Your will, whatever it may be. If they have not trusted in you as their savior, then we pray that they will learn of your great love for them. If they are in a physical relationship, that you will help them to repent of this and commit to purity in Jesus' name.
