Aah share house drama.

There isn't anything in there that screams racism.

Most of this is just classic share house bullshit and your bf should have checked with everyone before bringing your pets and belongings over. I also missed the part where you were doing anything to demonstrate that you were actively looking for somewhere else to live, rather than just presenting the household with the fact of your presence.

I mean, you really did put everyone else in a position where they could either let you stay or look like assholes for kicking you out. That's a dick move on the part of you and your bf. Your claim that you really truly were only there temporarily at the start rings pretty hollow and would have got nothing but eyerolls where I'm from.

Even if there is real discrimination here, the he said she said aspect will make this very difficult to resolve.

You're better off cutting your losses and getting on with your lives somewhere else, from a position of being open and honest from the start with your next set of housemates.
