Forgive and forget.
We never really forget, but we forgive for our own sake. Resentment hurts the one holding the resentment.
Family drama is in all families. Cutting oneself off from half the family leads to more misery for everyone involved. Forgiving stops all that. If someone has harmed you or your wife, it is to your benefit to forgive them. If they continue to act in a way you feel is unkind, you address it right then in a kind way. Then move on.
