Hey Reddit,

My younger brother has been with his girl for about a year, maybe 1.5 years. He's 18 now, so still young and naive. I've introduced him to RP principles and while he's refused to go single and spin plates since he wants to actually be in an LTR, he does come to me for advice since I can usually provide a RP perspective on things.

He just told me his girl broached the subject of an open relationship with him. Not to ask him to do it, but just to ask his thoughts on it. He immediately said no, which is good. But now he wants my advice in a couple minutes.

How do I break it to the poor kid?
