So - it’s love, adoration, worship of you - but only if you do what he wants?
I don’t have to tell you how many different forms functional relationships can take - living together, living together on non-kid weekends, not living together until kids are adults, never living together… sensible adults balance the needs of their separate families, even if that means some delayed adult gratification.
Looking objectively, it seems that he ONLY wants the option that affords him more space and your resources (space, money, time).
maybe don’t channel your inner rage and/or sense of injustice. Channel your inner need for peace and quiet. He is exhausting. And you do know, if you ignore him for a bit you get a break from hearing about what he wants.
