Her memory of you being raped is an episodic memory. Episodic memories are memories of our daily lives, such as what we had for breakfast, when we went to work, or in this case, what you told your friend. Everybody has failures with this type of memory. I understand why you're upset that she forgot he raped you because that is a very traumatic event, but I think because she is on good terms with him, she had a brief lapse of memory regarding what you had told her. It's okay to feel upset, but remember she didn't do this intentionally. It seems she feels really bad about it, so I think it's best to forgive her and remember it doesn't mean that she doesn't care or wasn't listening. Our memory isn't perfect.
