We understand the deep hurt and confusion you're experiencing. Firstly, we want to commend you for your decision to stop sleeping with him. It is clear that you have conviction and a sin conscience. This is a very important and godly step. This is in keeping with scripture since fornication is a sin. The fact you are no longer participating in this activity is a great step toward seeking God's will.
1 Corinthians 6:18 WEB "Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body."
As for marriage, it is clear that God takes it seriously. It is not something to be entered into lightly or promised without follow-through.
Matthew 5:37 WEB "But let your 'Yes' be 'Yes' and your 'No' be 'No.' Whatever is more than these is of the evil one."
Your feelings of heartbreak and doubt are valid, but we want to remind you that your worth is not defined by someone else's actions or promises. You are precious in God's sight.
Psalm 139:14 WEB "I will give thanks to you, for I am fearfully and wonderfully made. Your works are wonderful. My soul knows that very well."
It's important to seek a spouse who shares your faith and respects God's principles. We encourage you to pray for God's will in your life and for a godly spouse who will honor and cherish you as Christ does the church.
Ephesians 5:25 WEB "Husbands, love your wives, even as Christ also loved the assembly, and gave himself up for it;"
You asked if you should desire a wedding. It is good to desire marriage if it aligns with biblical principles. God Himself performed the first wedding ceremony and it was good. You should want to be married if you desire to live a life honoring God.
Genesis 2:21-24 WEB "Yahweh God caused a deep sleep to fall on the man, and he slept; and he took one of his ribs, and closed up the flesh in its place. He made the rib, which Yahweh God had taken from the man, into a woman, and brought her to the man. The man said, 'This is now bone of my bones, and flesh of my flesh. She will be called Woman, because she was taken out of Man.' Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh."
Now let us pray together.
Dear Heavenly Father,
We come before You, lifting up your daughter who is hurting and seeking Your will. We pray that You heal her heart and help her to understand that her worth is found solely in You. We pray that would you turn her heart toward you and away from the heartache she is feeling. We pray that You guide her steps and bring a godly spouse into her life who will love and cherish her as You do, if it is your will. Jesus Christ, you said in John 14:6 WEB "I am the way, the truth, and the life. No one comes to the Father, except through me." We ask for your forgiveness for the sins of fornication and anything else that may have happened. We ask that you are the center of her life and all her relationships.
Finally, we pray that she finds encouragement from Your promises and that her faith in You will be strengthened. If she is burdened with any sin, we pray she will confess it to you and have forgiveness.
We pray this in Jesus' name, "If you will confess with your mouth the Lord Jesus, and believe in your heart that God raised him from the dead, you will be saved." Romans 10:9 WEB
