My rule of thumb: “Forgiveness is a gift. Trust is earned.”
Let go of the anger and realize you still probably cannot trust things he says. Those are two separate issues which people routinely mix up and think are the same thing. Abusive people actively encourage that confusion. They want you to “forgive and forget” — basically saying that in order to forgive, you have to trust them blindly and let them do the same damn thing to you again, like a sucker. No, you don’t.
