IMO Paul trying to Con us all at home that he s soddenly become someone who cares if he upsets others and suddenly turned into this regretful guilty ,empathetic person is complete BS .Alter a weeks long of deliberate plotting against Sarah who's he trying to kid ?

I believe he suddenly cares what people will think of him once his aggressive side subsides.

He has always been like this, and it was no different during the first week. Only person he had an argument with then was Sarah, and he tried to apologize to her on the same day (was ignored) and then did it again the following day. No difference.

No don't believe it. Paul is a complete dickhead and likes to be centre of attention. He is one of those guys who spends much of his life apologising to people...because he loses his temper too often and comes out with nasty stuff..then apologises.
It's not sincere...until the next time
