The other stand-out line was, "She says that she doesn’t like the person that I am. This came out of left field." -- I think some more reflection on 'that' might be in order. Like, what in particular makes her dislike her 'mom' "over-all"/as a person?
In my mom's case she would say outlandish things that would just beg for someone to say, "You really believe 'that'?" because her belief was either flat-out 'wrong' or just not in tune with reality.
For example, she wasn't homophobic but, she didn't 'like' that so many TV shows had openly gay characters that were in relationships. Like it's okay to be gay, just don't have a same-sex relationship and yet no objection/comment on hetero couples. So she's kinda homophobic which doesn't work for Me.
Of course if you challenged that view, then the fire-works would begin... That's not how she means 'that' and even if you said, "Well that IS how you meant IT." and then the pathetic, "You think I'm a bad person!" and I used to comfort her because, you know, "Poooor MOM..." YOU made HER feel 'bad'.
As I've said before, now that I'm out of the FOG, maybe she SHOULD feel "bad" because she has a 'crappy attitude' which is the polite way to say, she's a disgusting Covert Narc abuser.
And no... There is little hope that relationship is gonna survive. No Contact is in 'mom's future which is sad. Daughter put everything 'out there', 'mom' knows what the issues are and is still acting like there's just "nothing she can do".
