and yeah
Porsha is mad she no longer has a leg up over Shamea and that the dynamic changed. Shamea has the life she so desperately wanted, there's jealousy there and we all see it.
Shamea was always playing second fiddle to Porsha and she never felt that like she was that gorl, and now she's overcompensating and trying to prove something.
This really comes down to insecurity on BOTH of their parts.
