It won't last. I love Porsha but she does have a very childlike sense of loyalty. Kenya is gonna throw some lite (late) shade about Porsha stealing a married man and then Porsha gonna reach for her gun.
But at the same time, Kenya doesn't necessarily want it to last. Lol she already said she wants Porsha back cuz she need somebody to "play" with. However, their friendship would probably last as long Porsha doesn't return to the show.
