Maybe being separated from Ward and June is the best thing for now. Obviously there are issues in their marriage that need to be taken care of, and it doesn't seem like they are entirely prepared for a poly relationship at this point.
You say you weren't getting enough emotional intimacy from this relationship anyway. Perhaps this is a good opportunity to move on. If they sort out their issues and Ward still wants to be with you, give it a shot then. But it's probably not a good idea to be in a poly relationship with someone who can only "take care" of one relationship at a time.
