Perhaps the 'cuckold' situation is just a misperception.

So, when it seems like one is being cuckolded, it's actually all part of a planned exploration of their relationship boundaries.
A plot twist might be that the new spouse who is getting close to the other person is actually being blackmailed or forced in some way. Maybe there is a past acquaintance of the other person who has something on the new spouse and is making them act in a way that creates the cuckold situation. This could lead to a whole new set of revelations and reconciliations.
