I like your thinking. Allison might have confronted him about Toni being there the next day. He might have got worried that the two women might talk to each other at the conference and that Allison would find out he was seeing Toni again and/or that he'd said he would leave her. That might have prompted him to do this or he might have been going to do it re the money situation anyway but he upped the timeline because if Allison told others and left him the chance of him being the suspect after that would escalate.I find myself agreeing with you a lot Mumma Bear I think the timing of the counselling session on Monday (?) was not coincidental. And the 15 minute Q&A session on the Wednesday night. I hate to say it because I feel like it's putting an unfair burden on the counsellor, but I think it's very possible that the Wednesday night 'talk' was a trigger or the final straw. That they went for a drive to have the talk (if you believe GBC) tells me that talk was more serious than previously. I think Allison felt empowered by the counsellor and more in control of things and this was not what was GBC was used to. And then that coinciding with the conference on Friday and his 'commitment' to Toni and the Thursday night phone calls. I would say he was most afraid of Allison finding out about Toni because if Allison walked, it would destroy his image. I think both Allison and Toni were upping the ante (ha I spelled it "anti "which would have suited) on him and he killed Allison. I'm still on the fence whether I think it was planned or something that got out of hand. A large part of me thinks it was something that got out of hand because when he says "I did not kill her" I think he really believes that. Oddly enough, the only coincidence that I think was just that is the timing of life insurance policy payments.
