LNL, He is just reacting because you are finally saying No more. He is reacting because his power has been diminished, and his reactions are to bait you into giving it back to him.
I've seen it all over the BB - as soon as the LBS starts moving on, the WAS gets angry, defensive, stubborn, mean... and it is all to protect the power they've either usurped or that the LBS has given them by being willing to do anything to get the WAS back.
At this point, I think you setting your boundaries is threatening your H, and he is reacting. Don't take the bait - let him stomp and pout, don't engage his tantrum, don't react. "I'm sorry you feel that way" is the most useful sentence in the book for these types of things.
