Finally watched last nights episode, I haven't read all comments on here so sorry if I repeat some.
I liked the scenes with Aaron and Liv, he did seem sad about Robert's mistake and the subsequent child, in my mind he was very very clear on the reveal episode that he forgave Robert for the ONS but he cannot be happy with the child (mainly PD+Child as that is the reminder of Robert's infidelity).
Liv was brilliant and basically said what we have all been saying for months.
(Please don't shoot me) But I know

is up to some mystery scheme at HF (I really do not know what his objective is I think I am missing the context) but his continual hanging around PD is never going to help Aaron see that he may have made the wrong decision, if I were

and kept seeing

& PD wandering around the village, in the cafe, in the pub I would simply think "thank god I made the decision I did as I would have to suffer that cow in my orbit all the time" it would surely make

more resolute in NOT softening towards

.
I think Robert is stuck in a cycle of doom, he hangs around with PD/Whites because he is scheming due to his break-up with Aaron, Aaron sees Robert with PD and thinks 'thank god I walked away" so he pushes Robert further away which leads to Robert thinking there really is no hope so he schemes and spends more time with PD and round and round it goes - the cycle has to be broken.
On the subject of Aaron, whats this immature obsession he suddenly has with VR, it really does seem like his way to escape the real world ???
Finally, how the hell do Aaron and Robert make any money they are never at work or maybe we are just meant to believe that Adam is dealing with HolyScrap and Jimmy/Nicola are managing Home James so Robert can make his mark at HF .... its all in the context of course - silly me.
