I call her the five-s - superior, snobby, sanctimonious, sentimental, and self-involved. You can't win with some people, every time I try to interact it ends up with her telling us all how great she is, how awesome her life is and how much better she is than we (me?) are. I gave up a couple of years ago - don't engage. Wouldn't mind if the cousins hung out, but she's involved in every interaction, so I avoid making plans.
She sounds like my SIL! I can also relate to the pp with the SIL who wrecks the curve - hahaha! Every word my SIL utters is either a brag or a criticism. A few years ago, after she received our wedding invitation in the mail, she called to tell me how much she spent on her invitations, five years prior. No other reason, just that.

I also gave up and don't share a thing with her. She's toxic.
