He turned it on me and said i am being silly its only a show nothing in it.
You having a 4 day hen do while he looks after the kids with male strippers/lap dances and a similar show with you eating a donut off one of strippers dicks - as long as you don't directly touch the dick ..... will be fine too then, won't it.
It would just be a show and hed be silly not to be 100% fine with it.
Problem is he's already done this/done it first.
So no matter what you do, there will be no parity.
He and his family sound sleazy, vulgar, low standarded, sexist etc.
He's also apparently one of those men for whom impressing and bonding with mates is more important than their partner's feelings, and decency to their partner.
And he's purposefully really trampled all your reasonable boundaries and expectations. You told him what youd (just about) accept he went way beyond it, he deserves to go, and he knows it, in spite of his gas lighting.
He thinks you'll put up with it cause you're stuck/trapped/too heavily invested.
Bear in mind he'll continue thinking like that.
