Both appear to be back in their respective countries and have made some statements about each other without directly tagging or talking to one another.
While it hasn’t been explicitly confirmed by Rose or Big Ed, the general consensus online (which can be wrong) is that the two have split since 90 Day Fiancé: Before The 90 Days ended.
At this current point in the series, it’s less surprising that this romance failed, though we’ll have to wait and see whether either of these two are on board for another season if given the opportunity.
