My newest addition, Moose, is like this! All I can say just keep being patient, you are taking the right steps.
He is just finally enjoying pets, but only when the mood strikes him (usually after meals), and I’ve now had him since May!
As for grooming and all of that, I’ve had luck brushing Moose while he’s busy eating his pellets.
She sounds like a playful and food-motivated girl, so also try teaching her some basic tricks (Moose picked up “spin” really fast https://www.youtube.com/watch?v=RERLARS9goQ) to help build your relationship. Bunnies all have very different personalities. Some will snuggle and want pets all day, others would rather play games with you.
The other think with shy bunnies is to wait until they are relaxing (usually after a meal) to try to pet. My Bunston was VERY shy at first, and what worked was to lay on the ground near him while he was lounging for a while. Then to “ask” if they would like to be petted, you should place your hand on the ground in front of their nose, pinky side down, so the back of your hand is facing her. If you just reach for the top of her head without “asking” first she might feel like you are going to grab her. If she puts her head down, then she wants pets! Petting with the back of the hand first usually helps them feel secure (like you aren’t going to grab them). If she doesn’t, gotta respect that.
