You're right that the D will change things. If/when you get into another R, that will changes things too. I'm not surprised he said nothing. What is there to say to that. It isn't about being mean or blaming IMO, it's just a fact.
Your R may be better right now b/c he feels like the pressure is off (and he still gets to do what he wants). I hope it lasts for you and that you two can find a way if that's what you want.
