Call me crazy but I think Rick was right in this scenario and Wong and Unity were dead wrong. Rick shouldn't feel obligated to pick up the phone for Unity or entertain her messages when they broke up on bad terms. He essentially blocked her which is what most people do with their exes when the situation was bad. The only reason this whole situation had an opportunity to go left is because Unity barged her way onto the planet uninvited and started taking over an entire state.
