Can My Husband Kick Me Out Of The Bedroom? House?

Location: Washington State, USA.

My husband announced he was done with me a week ago today (Saturday) and has since kicked me out of what was our shared bedroom. His reason is “boundaries.” He’s angry I spoke to a mutual friend about the circumstances around why he left me, and a contract he was trying to draw up. He feels it threatens his social standing and that I should not do that and that he’s not safe if I have information about him.

I understand not sleeping beside each other because it’s uncomfortable. My specific issue is that he says I’m not to enter the bedroom, and the bathroom and closet behind it without permission now. Even when he’s not home. My things are still in there.

Can he do that? I have such a problem being told I can’t enter a room that was ours less than a week ago. I’m an adult. Asking for permission to move through my home feels so weird to me.

The contract he wrote up set ground rules for how he wants the house. One of those “agreements” (I agreed to nothing) was that I‘m expected to vacate the house (sometimes with our children) for up to 24 hours at a time so that he can bring his partners over comfortably. I reached out to our mutual friend for a gut check and the mutual friend was equally appalled. My husband (he wants to remain married for tax purposes but operate as separated) then found out I had done that and blew up. He retaliated by banishing me from the room, after just that morning saying it was okay to continue to come and go and leave my things in there. We mutually agreed not to sleep beside each other, but the rest remained shared space.

I’m really lost right now and sick to my stomach. He told me if I can’t agree to not “sabotaging his social standing with friends” then he can’t have me in his life or house and things will get “nasty” and impact the kids. (The implication is that he will force me to leave or make it so hostile I have to choose to go.)

What do I have a legal right to? Can he enforce consequences on me if I go in anyway? Can he make me leave for talking to others about what’s happening?

More contex:

He required me to sign a prenup before we married last year that voided my rights to claim the last eleven years of cohabitation, in exchange for $10k/year for every year living together. I’m also entitled to no assets at all. We had to rush the prenup because we -had- to marry before the end of the year or the tax burden would be insane after we sold his previous house for 1.1m in profit. I was allowed access to none of this, nor claim over the new house, but he pays for everything so I didn’t argue. We started the prenup in June or July I think? And it had to be finished quickly so there was a few months waiting period so it couldn’t be seen as rushed. We signed it in August and married in November, and eleven days into our marriage he completely changed and began having relationships with other people, staying out all night, not telling me things, etc.

What I’m getting at is I have no legal ownership over anything. He will continue to cover the kids’ expenses but all of my personal expenses (therapy, animal food for my chickens, food I’m not cooking for the family, etc) is on a timeline.

He says I can remain living in the house with the kids as long as I can be okay with his partners being over. Yesterday he asked which bed I prefer he has sex with them in ”when the time comes”— our previously shared bed or my new one in what was the guest room.

If I can stay married on paper for a full five years, I‘m legally entitled to 5% of his current house value. That combined with the $10k/year thing would be enough for the kids and I to start over somewhere. Not enough for a house but not nothing.

The problem is I wouldn’t have access to any of that money until then. And I don’t know if I can stomach being here while he brings people through.

I rambled but yeah: what can he legally enforce on me?
