Holding a grudge or not forget?

Anonymous
Is there a difference between holding a grudge and forgive but not forget?

Because a person told me that you have to forgive but not forget, however, when this thing is applied, that person thinks automatically that is holding a grudge, or he reminds the things. He told that if you remember the things is because you are still holding a grudge or you haven't passed that part, but then he is contradicting himself, isn't he?
