I think holding a grudge is not good for anyone. However, remembering details about who wrongs you and over what is important–you take measures to avoid letting them take advantage of you again. They have damaged your trust in them.
Your trust level in people should reflect how they’ve treated you. It should be possible to earn back trust over mistakes when someone truly regrets wrongdoing, but people should understand that this takes time and consistency. Anyone who doesn’t understand this is not worthy of your trust.
