Wtf? Is This Legal? We Are Being Evicted…

LOCATION: WASHINGTON STATE. My boyfriend and I rent a room in a shared apartment. We’re on a month-to-month lease, and our landlord uses the building as an Airbnb when it’s not rented. We've been having constant issues with our roommate, and now we’re being told we have to move out by the end of the month. I don’t know if this is even legal or if we have any rights here. The situation: * Our roommate has been verbally abusive to me, calling me “slut” and “whore,” leaving petty or aggressive notes, and making false accusations. * She constantly complains about our things in shared spaces (like the coffee pot or rice cooker), even though we keep the space clean. * She leaves the front door propped open, which has brought bugs in. When we close it, she accuses us of “blocking her dog’s water bowl.” * Most recently, she accused me of putting glass shards in her dog’s water, which is completely false and obviously malicious. * We have gone out of our way to be respectful and non-confrontational — even communicating through polite written notes since she avoids us verbally. * She removed the smoke detectors from the unit. We told our landlord, who came to fix them and told her to figure out how to communicate or move out. * Instead, he told us (ourselves as well as our roommate) today that he’s terminating our tenancy because he’s “tired of the drama.” And “if one of us needs to go he has to terminate the contract with both parties” We now have two weeks to find somewhere else to live, and we have no money and no backup plan. I feel completely blindsided and punished for trying to be respectful in a toxic situation. What I need to know: * Is this considered a wrongful termination of our lease? * What are our rights in a situation like this? * Does an accusation like the one she made (about the dog) open us up to legal trouble, even though we didn’t do it? * Can a landlord legally kick out both tenants instead of dealing with the actual problem person? This whole thing is making me physically ill with anxiety. I’m exhausted, and I’m scared we’re going to end up homeless because of someone else’s lies and our landlord not wanting to deal with it. Any help or advice is appreciated.
