In their defense, that seems like an accident not an incident because they aren’t lucid or aware of what they’re doing in that moment.
They didn’t ACTIVELY participate in cheating behavior, so I think they get a free pass just the one time.
But it also depends like why were they in sleeping proximity of someone else when they are (or if they are) aware of their sleeping habits? I’d say this is very situational but I’d give the benifet of the doubt.

okay guys genuine question (im not trying to say this is ML at all) but:
is it considered cheating if your partner, who has a habit of doing things when they’re asleep, does something raunchy with someone else while they’re sleeping (fully unconscious)
