My friend is being envious and i want to block her at this point

In eid my friend mentioned that her cousin that disappeared out of a sudden and said that she was studying at a different city but all the family had suspicions that she was abroad showed up for eid for the first time in two years and she wa different, my friend mentioned that and talked about her for a while then she let it go, about 10 days ago they figured out everything, her cousin joined fly emirates about two years ago and removed her hijab and she is living her life and the only reason she came back this eid is because she is getting married to someone living in dubai, in the process of all of this she ended up adding my friend on insta to talk to her, and now this all what she want to talk about, sending me screen shots of her cousin's life and saying " look she visited Vietnam" "look at her swimming in a swimsuit in Italy" "this bitch went to Russia", and now if has gotten to a point were i know for sure my friend is being envious of her and I'm over it, and every time i say something about her cousin being a person of her own and having her own decisions she clapps back with the way her mom used to shame her in comparison
