Yeah, I agree. I think she lied to me because she was lying to herself, in a way. When she denied a memory I had of her (April 2019) from when I was younger, it was selfish because it was done to protect her self image rather than acknowledge my feelings, the hurt/pain/trauma she caused, she was more concerned about protecting her image than processing my feelings. She proceeded to tell my dad about it and apparently he said something like “that doesn’t sound like something you would say”, which she proceeded to tell me about to further paint the image that my memory was false. To give her further reassurance from my dad that her self image was protected and unthreatened in any way.  Essentially she has convinced herself that I made up a memory of her.  Maybe it’s a subconscious defense mechanism, or she really is selfishly lying to protect her self image of being a “good” mother.
