Parents Want Me Out Of Their House. How Much Time Do I Have Left?

My parents and I got into an argument the other day and they attempted to lock me out of the house when I decided to spend the night with my SO I ended up calling the cops and they essentially told me that I can’t be evicted in that manner and that I’m good to live here for now. I have been paying them rent for the last year and a half and have all my bills, bank statements, etc. going to their address. I’m a student and need some time to figure out where I’ll go next. They’ve been avoiding me since this happened and I don’t know what to do or how much longer I have here. I’m in WA. I have plans of getting an apartment but that won’t be possible for another couple of months.
