If your long term partner seriously suggested an open relationship, would you to breakup?

Would you hear them out, and give them a chance to explain?
Would it make you want to quickly break up?
Would you ever even entertain the idea?

My friend told me this happened with an ex of hers, and I was like, I don't even know wth I would have said if that were me, because for me, it would make me think he was already cheating and now just needed permission to do so which even the thought, makes me want to vomit. Obviously she broke up with him. I'm like her, like, I didn't sign up for a three way call, ok!
