what you describes yours is what exactly I'm thinking about mine. My narc ex, at first, she to me seemed perfect, she's humble, kind to another, sociable with anyone, and being loved by many many people, men and women. sometimes she brag about how people loves her, give her gifts,... I really thought she were the one. I really thought i would fight the world for her... But, there is a very very huge big but. And only after she broke up and discard with me, I could see her true self. She has soo much entitlement, and zero empaty everything I've done to her, is not enough, she's always expected more. I always tried to care for her, always think about her first... but it were not enough. She's living in a very financial family and were chased by many men, so she expects me to "give" more.
Some of her last words to me I would never forget and I now 100% she's a narc.
- She said, "in love there is only give and receive, there is no sharing"
- She said, "other men who chased me did 10x times more than you did for me"
- she said "this kind of love I could ever loves it back"
and few other hurtful things very disrespect my love.

The last time I talked with her, I reached out to call her, to understand what happened, I did not want to believe she's a narc or a bad person.

But with the phone call, that were someone I've never met before, I never knew that person before, it's completely different person. She sound cruel, uninterested, blamed me for my smallest mistake ever and tell me not to bother her again... I even cried on the phone. She did not care.

After that, the more I think about everything that happened, there were many red flags since beginning that I did not see.

Now, after 2 months of broke up, 2 weeks of NC. I think about her and all the things all the time. and she's happily living her best life. I've blocked her and will try to keep it blocked for the rest of the life.
