You just articulated the plan. My resistance to being a bee'otch has been that I don't want him to feel "justified" in leaving. I want him to have seeds of doubt planted everywhere. And honestly, I feel lucky that he still wants to have 'relations', etc since so many others here have spouses that claim to hate them, etc.
Once he has actually made the move, I can employ a different tactic.
