Too bad for him about the bed. He can get a sleeping bag.
He can get as ugly as he wishes, but in the end, your L will help you get what you need for your S and you.
Why they have to act like snapping dogs when they go through a MLC, I don't know. But, my H acted like someone I didn't know, too.
I don't think you did a darn thing wrong, he said take what you want, you took what you wanted, and he should just live with it. I hope you were able to get everything else you wanted, including S's stuff.
Sorry it was so rough for you today frown
