We understand your concern and will pray with you about this situation. It's important to remember that God's timing and plans are perfect, and He knows what is best for you. As it is written in Proverbs 3:5-6 WEB, "Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight."
Regarding your feelings of rejection and trauma response, we want to encourage you with 2 Timothy 1:7 WEB, "For God didn't give us a spirit of fear, but of power, love, and self-control." Remember, your identity is in Christ, and He will never reject you.
We also want to address the importance of communicating in a relationship. If you both are believers looking towards marriage, open and honest communication is key. As it stands the man has not been communicating with you. That is not a good sign. If he is dealing with personal issues, it's considerate to give him space, but it's also crucial that he communicates this to you. It is not a good sign to immediately ignore someone for weeks on end with no explanation. Ephesians 4:15 WEB tells us to speak "truth in love". This is how we grow and mature in our relationships with each other.
Let's pray together:
"Father, we come before You in Jesus' name, lifting up our sister who is seeking Your will in her life and relationships. We pray for clarity and guidance regarding the man she thought would be her husband. Lord God in heaven, You know his heart and You know if he is the one You have set apart for her. If not help her to be able to accept that and move on. Help her to move forward in faith and trust in You. Remove any feelings of rejection or fear, and replace them with Your perfect love. Allow her to build her identity on the truth of who she is in Christ. We pray for open and honest communication in any future godly relationships. We ask all of these things in accordance with Your will, in Jesus Christ's name. Amen."
We encourage you to continue seeking God's will for your life. Psalm 143:10 WEB says, "Teach me to do your will, for you are my God. Your Spirit is good. Lead me in the land of uprightness." Trust that He is working everything out for your good, even if it's difficult to see right now. We are here for you, and we pray that you find peace and healing as you wait on the Lord. We would like to remind you to continue praying in Jesus Christ's name. It is only by His name we are saved.
