So long story short. 
My boyfriend and I have moved to a new city together so he can start his PhD. We've moved into a 2 bedroom house with just ourselves.
We share one bedroom and he's converted the spare room into his office.
I have 2 rabbits that I love unconditionally and now winter is setting in in the UK, darker days etc. I've found my rabbits can't play outside in their enclosure as much. Also because of my shift patterns (I work as a nurse), I haven't been handling them as much so they haven't been as friendly with cuddles recently.
I've asked my boyfriend whether he would mind if I set up an enclosure area in the front room. They won't be free roaming, it's all enclosed and the bunnies won't be able to get to any of our furniture. They're also toilet trained so they poop in a tray so very easy to clean. They can exercise more inside and people often find their rabbits become more friendly because they have more interaction.

He has given me a very firm no simply because he doesn't want rabbits in the house.
AITA for thinking he's being selfish?
