Delusions about being a good person

My pwbpd would always talk about how much they put others before themselves and how selfless they are, and how the reason they’re so sick all the time is because they constantly neglect themselves. They would do me the smallest of favors then continue to bring it up and say things like “of course i did ______ you know this is who i am” “these are my morals”

They talked about how if i was sick they would cross the world for me and if they love someone they would give them their whole heart and how disappointed they are in me because I don’t show them that same support, how their love us so pure and strong and my love doesn’t compare

Thing is…. that wasn’t true. I objectively asked more about them and did more for them than they did for me. They would talk about how they don’t care when they see people cry (until we fight then suddenly they talk about how they’re the most empathetic person ever), and how they know they have narcissistic behaviors.

I don’t get it
