Is it love or hate?

I adopted a 3 yr old bunny back a few months ago. She bit and grunted at me if i got too close at first but she’s warmed up. lets me pet her now and seems to like it. i give her tons of space and don’t force her into anything, i think that helps. if she grunts or seems displeased i immediately withdraw. she hadn’t bit me in awhile until today. i was petting her, her eyes closed and she just chilled. i would periodically stop and she would nudge my hand to keep going. when i reached my fingers to her head she bit my index hard enough to leave a mark. does she hate me? or is that a love bite like cats do?
