That said one can never be too sure how serious feuds are on reality television, especially on Jersey Shore Family Vacation.
Jersey Shore fans know the two have a long history of pissing each other off, and a sleight like this could be enough for Ronnie to skip out on the wedding if Jen is indeed not allowed to attend the ceremony.
In all honesty, whatever happened in that episode might be null and void, as Ronnie might reject his invitation after seeing what Mike said during the episode.
