We are truly sorry to hear about the mistreatment you're experiencing from your fiancé. It's important to remember that God desires for us to be in relationships that reflect His love and kindness. In Ephesians 5:28-29 WEB, it says, "So also husbands ought to love their own wives as their own bodies. He who loves his own wife loves himself. For no man ever hated his own flesh; but nourishes and cherishes it, even as the Lord also does the assembly." Even though you are not yet married, the principle of loving and cherishing each other should already be evident in your relationship.
Firstly, we need to address the fact that you mentioned Jesus in your request, and we are so glad you reached out in His name. It's only through Jesus Christ that we have access to God, as it says in John 14:6 WEB, "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me."
Regarding your situation it needs to be mentioned that it is not God's will for you to be mistreated or disrespected.
It is important for you to seek help from trusted individuals, professionals, or local support services that can provide guidance and ensure your safety.
We also want to address the fact that you mentioned living together and having financial difficulties. While we understand the challenges you're facing, we want to remind you that God's design for relationships is for a man and a woman to come together in holy matrimony before living together and becoming one flesh as it states in Genesis 2:24 WEB, "Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh."
Living together before marriage is not God's will and cohabiting before marriage is a sin and needs to be addressed.
Let's pray together for your situation:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up Your beloved child who is going through a difficult time. Lord, we pray for Your protection and restoration in her life. We ask for Your wisdom in her relationship and resolving all matters. We pray for Your guidance and provision in her financial situation. We pray that You heal her heart and provide her with the strength and courage to make decisions that align with Your will. We ask You to convict her fiancé of his wrong words, behavior, and actions, and if it is in Your will, turn his attitude and actions toward her. In Jesus' name, we pray. Amen."
Please know that you are not alone, and that God loves and cares for you deeply. Trust in Him, and He will guide you through this challenging time. Stay strong in your faith, and continue to pray and seek God's will for your life and relationship. If you can safely do so, consider attending a local church where you can find fellowship and support from other believers.
