I agree. I really don't want to see Aaron, Robert and Liv mixed up in that hideous story line.
Looking at the spoilers, I think their involvement is only on the fringes of the child abuse story. In the next few days, Jacob is going to put a lot of distance between himself and his abuser. He will try to stay out of her way by spending time with his friends, Gabby and Liv, so that she can be alone with David. Maya gets jealous and tries to keep Jacob away from Liv's company by causing problems between her and Aaron. Maya knows that Aaron, and probably Robert, are not too keen on Jacob.
