Hi there, welcome
Sounds like they are getting close, but haven’t quite sorted things out fully yet! You’ll want to see a decent amount of cuddling, and at least some grooming from both buns. What happens when a grooming request isn’t met? Do they end up snuggling? Or does one move away?
It’s not like every single grooming request has to be met (my pair is VERY demanding of each other in terms of grooming, so half the time they just fall asleep with their faces smooshed together lol), but you should see at least some! And if a request isn’t met it shouldn’t end in a scuffle or with too much fuss.
Not sure how long your sessions are, but with mine I didn’t get grroming breakthroughs until we were in pretty marathon sessions.
