Oh my - yes, that's the very definition of cake-eating. And the fact he can even suggest it when you believe he's probably been to a solicitor and knows full well what yours and his rights and responsibilities are suggests he's flailing a bit with facing up to the reality of the situation.
Is there a time-limit on these discussions? I can imagine nothing much productive is happening as he seems to want some of the financial benefits of being married without an actual married, or any of the responsibilities - and you, quite rightly, aren't going to let that happen. That seems intractable, so perhaps it's better to stop the conversations and start some healthy action.
I'm sorry you're having a hard week. It just keeps on coming, doesn't it? I hope the CBT is helpful to you and helps you get unstuck from the tunnels you're in.
