AJ & McCall: Third Wheel Roommate Debate @8

AJ & McCall are being called on for their advice as two roommates are about to come three. Roommate X lives with her best friend but that could soon include her roommates boyfriend. Roommate X doesn’t get a good vibe from the boyfriend and isn’t a fan of him moving in. Does a roommate have veto powers for significant others moving in for the Debate At 8? Can a third wheel roommate actually work?
