As a pastor, I've seen many situations where people are torn between what to do in a difficult situation. In this case, it seems like you're facing a breach of trust and are unsure of how to proceed. My advice would be to take a step back, pray about it, and seek guidance from the Lord. The Bible says to "distinguish carefully between what is truly right and wrong" (Ecclesiastes 5:2). This means taking the time to reflect on the situation, considering all the facts, and seeking wisdom from God's Word.
It's also important to remember that sometimes, the right thing to do may not be easy or popular. In fact, it may lead to more problems in the short term. But as a follower of Christ, our goal is to do what is right, even when it's hard. This may mean being silent and submissive, as 1 Peter 3:1 suggests, or it may mean taking a stand and addressing the issue head-on. Whatever the case, it's essential to prioritize honesty, integrity, and fairness.
In terms of specific actions, I would encourage you to seek counsel from trusted friends, family, or a spiritual advisor. It's also essential to consider the impact of your actions on all parties involved, including your children and friends. Remember, the goal is not to "win" an argument or "get even," but to do what is right and honor God. As the Bible says, "Do not be rash with your mouth, and let not your heart utter anything hastily before God" (Ecclesiastes 5:2). Take your time, seek wisdom, and trust that God will guide you in the right direction.
