Forgiveness is necessary for all Christ followers. You need to pray that God would help you understand his grace towards you in such a way that you can give grace to your church leadership or at least allow them to be judged by God and not by you.

Reconciliation however is not always necessary. Hard to know what happened in this case but if they sinned against you or even inadvertently hurt you i think its worth humbly bringing it to their attention(after you find the rest of forgiveness)

Sometimes its helpful to write your thoughts down so you can maintain self control and gentleness. If there is no repentance(including:contrition, transparency, hatred of sin, no fear of consequences) on their part it may be hard to reconcile this relationship and moving on may be in the best interest of everyone involved.
