Oh and as for the cheeriness about reorganizing his room? Typical MLC behavior. When my brother had his MLC and dumped his 3rd wife, he took her with him to see the new furniture he'd bought for his new singles pad! It's like their brains can't separate their excitement at their new life that they want to share with the person they are leaving behind in the old life!
BTW - if you want a tv, ask around. People upgrade their TVs so often now, you might have a friend who has an old one they could lend you or give you, or you might find a used one very cheap online.
It's good you're not attached to the material things - like the alexa nonsense. It's good to have some bargaining chips though so don't let him railroad you into giving him everything he wants.
