Hmm, I have read a lot of this thread and I think my dm might be a narc. What do you think?
When stepfather used to beat me up (he did this repeatedly with fists for about 6 years, till i left home): 'no man would accept a 10 year old talking to him like that, what do you expect?'. She since denied all knowledge of him abusing me until tricked into admitting it 20 years later. She also used to say that I would grow up and leave one day so she needed to stay with my stepfather (they have since divorced though, when I was an adult).
On my personality, generally: 'you've always been difficult and unpleasant, since your sister was born' (just before my 2nd birthday) - I grew up thinking I was just an awful person.
My dsis was 'selfish' because she told my dm she wanted a small wedding and would not be inviting dm's friends. Apparently, dsis didn't understand that her wedding was about her family, more particularly about her dm, not about her.
Dm told me once that she would get cancer from all the stress I was causing her and it would be my fault.
Dm told me that I broke up her marriage to my df (which is strange, because I thought her leaving my df for another man is what broke it up).
She comments on my weight every time I see her, although positively if she thinks I am looking thinner. Being thinner obviously makes me a better person 
The weird thing is, I have a ok relationship with my dm now, although she genuinely thinks she was a brilliant dm
. I guess distance helps.
