Oooh those Dutch rabbits can be very opinionated!
Is the bunny spayed? If not, that could explain a lot of the behaviors! Spaying is also important to prevent reproductive cancer. Can you ask your roommate to get a taller pen so the bunny can’t escape? That seems important for safety issues too.
In terms of bonding with the bunny, do you notice a particular trigger that might cause her to attack you?
Hand feeding is always a good way to win over a bunny, but you have to make sure you aren’t rewarding her attacking you. Sometimes the best course is to ignore the bunny to the best of your ability. Maybe when she’s calm and your roommate is there, you could try sitting on the floor with her to start building some positive associations?
If she bites you, squeal loudly (” EEEEK EEEEK EEEEE”) to let the bun know she hurt you. If you need to move her away from you, push down on the top of her shoulders and turn her that way (don’t put a hand near her face).
