We are truly sorry to hear about the pain and hurt you are experiencing in your relationship. It is clear that the actions of your fiancé have caused you significant distress, and it is important to address this situation with wisdom, grace, and truth.
Firstly, we want to commend you for recognizing the issues in your relationship and desiring a godly resolution. It is crucial to remember that God's design for marriage is a lifelong commitment between a man and a woman, and it should be honored and cherished. The Bible tells us in Ephesians 5:25 WEB, "Husbands, love your wives, even as Christ also loved the assembly, and gave himself up for it." This kind of love is selfless, sacrificial, and unconditional.
Your fiancé's behavior raises serious concerns. His prioritization of his ex-girlfriend and her family over you and your family is not aligned with biblical principles. The Bible warns us in 1 Corinthians 7:2 WEB, "Nevertheless, to avoid sexual immorality, let each man have his own wife, and let each woman have her own husband." While it is commendable to be on good terms with an ex for the sake of co-parenting, it is essential to set clear boundaries and prioritize your current relationship and future marriage. His jump to assist his ex is making you feel left with scraps is wrong.
Moreover, his accusation of jealousy does not address the genuine hurt and insensitivity you are experiencing. The Bible tells us in Ephesians 4:32 WEB, "Be kind to one another, tenderhearted, forgiving each other, just as God also in Christ forgave you." It is important for him to acknowledge your feelings and work towards healing and reconciliation.
We encourage you to seek God's will in this situation and trust in His timing. It is crucial to be in a relationship that honors God and aligns with His principles. We advise you to surround yourself with godly counsel and support as you navigate this difficult time. Additionally, we would like to refer you to 1 Corinthians 7:39 WEB, "A wife is bound by law for as long as her husband lives; but if the husband is dead, she is free to be married to whomever she desires, only in the Lord." Remember the goal of courtship is marriage to another Christian Believer.
Let us pray together:
Dear Heavenly Father,
We come before You today, lifting up our sister in Christ who is hurting and seeking Your guidance. Lord, we pray that You would deal with her fiancé's heart and reveal to him the error of his ways. Help him to understand the pain and hurt he has caused, and guide him towards true repentance and change.
We also pray for our sister, that You would grant her the strength, wisdom, and courage to make the right decisions in this situation. Lord, we ask that You would provide her with godly counsel and support, and that You would guide her steps as she seeks to honor You in her relationship.
We thank You that we have access to your throne of grace and the right to make this request. We come to you in Jesus' name, as you have told us that what we ask in His name you will do.
In Jesus' name, we pray. Amen.
We encourage you to stay strong and lean on God for wisdom and understanding. Your prayers are always welcome.
Let's keep our focus on prayer, trusting God's timing for all interactions. "Cast all your anxiety on Him because He cares for you" (1 Pet 5:7). Continue in faith! 
Hello everyone! Let's lift up
