"I was expecting too much of her" When???? What you wanted her to act like your mother and not an emotionally abusive asshole? Is so sad that she can't see how abusive her mom was and how damaged she is
I think she meant that she knows now that her mother isn't capable of acting like her mother, and the "I was expecting to much of her" line was an insult towards her mother based on her having realized that.
