What you have described is a heavy and tangled burden, and it is understandable that you feel exhausted beyond words and unable to rest. The pressure that has followed you for many consecutive days, the slander you have heard, the fear about your future, and the threat of being publicly shamed would weary anyone. Your desire is right and good. You want only that the truth be told, and you want a little peace.
You spoke of how faith comes by hearing, and how hearing constant negative talk about the man you have hoped to know for nine months has begun to change your feelings toward him. That is a wise observation. What we repeatedly hear does shape our heart. When others speak evil continually, even if we do not want to believe it, it can plant suspicion and coldness. For this reason guard what you receive. If you have not had the chance to know this man personally, do not let the constant criticism of others become your judgment. Ask God for clarity from what you can see and know to be true, not from repeated slander. And on the other side, when someone in authority keeps pressing you to give a second chance to the man who ghosted you, you are not required to let another person decide your conscience. A relationship, and especially marriage, must be entered freely and willingly before God. It is a lifelong covenant of one man and one woman, not something to be forced by insistence or harassment. No pastor or authority has the right to coerce you to marry someone you do not want, and no one should demand that you explain yourself until you are persuaded to comply. You noted that this pressure itself feels like tyranny and that your limits have been crossed. It is right to set a clear boundary, to speak truthfully and calmly, and then to step back. If you spoke harshly out of exhaustion, bring that to the Lord and ask for grace to speak with firmness and gentleness, but do not feel guilty for refusing to be pressured.
You also carry anxiety about your mental and financial situation, and the fear that you cannot meet this person or be seen favorably, and that you are a failure because you are not yet financially independent. Your worth as an adult before God is not measured by your income or independence. God sees your diligence, your endurance under trial, and your desire to do what is right. Bring your practical needs to Him daily, seek wise and honest counsel for next steps toward stability, and do not let shame define you. Exhaustion and an overheated mind need rest, simple routines, sleep, prayer, and the support of safe people who do not use you.
The most serious part of what you shared concerns the congregation where you denounced one who harmed children, and now you are being threatened with a public interrogation to humiliate you. The Church is called to be the pillar and ground of the truth, to maintain the faith and to protect the vulnerable, not to conspire to silence those who speak about evil done to little ones. Do not prize a false peace above truth. Scripture teaches to give no unnecessary offense and to be at peace as much as lies with you, but if the cause of truth and the protection of the innocent is at stake, you must make a noble stand even if it costs you. That stand is not to be done with hatred in your soul, but with courage in your actions. Like the blind man who was questioned by those in power, you can tell the truth calmly without denying what you know, even when fear is great. You are not the guilty one for speaking about what was done. You said you were not even the one who first revealed it, and that other victims remain silent. God sees all of this. You do not need to submit to a spectacle designed to shame you. Seek wise counsel outside that congregation, bring a trusted witness with you if you must appear, keep a record of what is said, and if there is criminal wrongdoing against children, let it be handled by the proper authorities who are appointed to protect them. Refusing to be cornered and judged as a pariah is not rebellion. It is a right desire for justice.
Concerning the wedding in October, you were personally invited by friends you care for, who were married once in their home country and now wish to celebrate again where you live. You go to honor them, not to be a target. That is a good and right motive. You should not have to hide because you were harassed and intimidated. Consider going with a trusted friend by your side, greeting your friends, and having a plan to leave quietly if you feel unsafe or targeted. You do not need to answer interrogations or defend yourself at a celebration. A brief, kind greeting and a clear boundary is enough.
You said you feel hunted and made to be the designated wrongdoer in every story. God does not see you that way. He knows the difference between zeal for truth and the desire for control in others. He offers a peace that is not merely the absence of conflict with people, but peace with Himself that can keep your heart steady even when others are in turmoil. Pursue that peace through prayer, through the Word, and through fellowship with believers who love truth and show mercy.
I will pray for you. Father, give this weary sister rest for her mind and body, provision for her needs, and clarity where there has been confusion and slander. Give her courage to speak the truth without hatred, wisdom to set firm and loving boundaries, and protection from those who would use their position to pressure or shame her. Let truth be brought into the light concerning the harm done to children, and let justice and healing come. Grant her peace in Christ that guards her heart, and surround her with safe and faithful community. Lead her step by step, and help her to know she is not alone. In the name of Jesus Christ, our only Savior, amen.
