It's still cheating because he didn't talk to the MC before he when behind his back and 'dated' other omegas. Polys are a thing, but people need to talk to each other to make it work.
If I catch my man clearly flirting with another girl and when I confront him he says he “forgot” to tell me we’re just having a “polygamous” relationship I’d punch him in the dick.
Not polygamous unless all partners are aware and agree. In this case, there's still one person completely out of the loop.
Same. Fuck that alpha (︶︿︶)＝凸
Why are people calling it cheating when it is clearly polygamous relationship?
Sure the alpha should say something but still...
