I have read this comment before. It sounds to me as if it is from an "insider" who knows OP but is not necessarily loyal to him now. This "insider" has written other comments too alluding to the fact that OP was not as smitten or "in love" with RS as OP wants us to believe. OP has possibly demanded that Justin Divaris, Sam Greyvenstein and Graham Binge give the court this impression in their statements and they have been caught out in lying. Justin Divaris sold cars to OP so he has a vested interest in his relationship with OP for profit, Sam is his girlfriend and his cousin, Graham Binge is a family member. IMO they lied on OP's behalf to get him off on bail. I have been disappointed by them in their possible lack of integrity as Justin and Sam were the ones who introduced RS to OP on November 9, 2012. So where's their integrity and loyalty to RS? Was RS desperate to meet OP? IMO she loved him more than he loved her.
That is why I have never taken to the supposed jealous rage theory about Warren Lahoud seriously as the motive. It might have been just a coincidence that OP phoned RS twice at that time about trivial issues and he did not realise that RS was with WL at the time eg "Can you buy



for tonight?" "I will phone you back later about xxxx", etc. RS had probably not told OP that she was meeting up with WL.
Again, this is why I have been looking for more serious issues for RS and OP to argue about than RS simply meeting up with WL the previous day.
My gut feeling is that OP wanted to pursue Erin Stear at the time. I do believe that OP wanted to end his relationship with RS that night but she would not accept it. I do not think he planned to murder her at that stage. He just wanted to return to his mates for the guys night out. But RS felt cheated by him and thought she could resolve it before she went home. But OP continued to ignore her with conversations on the phone. He then could have felt so stressed that he took performance enhancing (or other drugs) and his behaviour became more aggressive. RS then realised that this was a side of OP that she had never seen before so she discovered his secret either innocently or by searching for it while he was on the phone ignoring her and the evidence was there that he had been a drug cheat. She then confronted him about it and the rest is history. With his being exposed to RS as a drug cheat, OP in the end decided that RS had to go that night as that was his worst fear.
This is only my opinion and speculation.
