If I may, it's pretty clear that most mamono imprint upon the first man they have sex with, or the first man they have sex with that actually reciprocates their feelings. It's rather unclear if they have preferences or just take literally the first man they ever see.

Now, the imprinting alone is enough for a mamono to consider herself married, even if no actual ceremony takes place. But if a mamono keeps you around, or refuses to leave by herself, shows a lot of affection towards you and never has sex with any other man anymore, you can be pretty certain she considers you her husband. They can have traditional marriage ceremonies, but that seems to be purely for show; as the Mamono would only do that to the man they've already imprinted upon.

As for the OP's question : Mamono don't cheat, ever. At least, not willingly. It's both because they consider disloyalty towards their beloved partner something unthinkable, and because due to their instincts they cannot tolerate the taste of any man's spirit energy besides that of their husband. So even if one has no objections to cheating, they probably can't bring themselves to do it since it would be very unpleasant.
