Maybe as a point of discussion. You can say "in a healthy relationship there's discussion over how money is spent"
"In a healthy relationship both parties have a say in expenses"
"In a healthy relationship both parties have spending money"
"In a healthy relationship both paid work and home work is appreciated"
"In a heathy relationship both sides are aware of costs and household expenses"
You are trying to state things clearly not in a "I don't love you any more" way. This is fact. Then when he replies it to others or his mind he can be the way to say "she's crazy- she think we should have a partnership- she thinks both work and housework should be valued" all stuff that make him sound like a right tosser to any normal person going.
Once you have had the big chat I would stick to repeating we had this conversation. The only things left to discuss are housing, access, maintence. Be firm and clear. You will state facts to his face he proble not get it or argue these things don't matter. But then refuse to engage further in pointless discussion.
