A little back story, we had two bunnies, a male and female, that were bonded.  The male had a health issue that came up that, while fixable, we were unable to afford (thousands of dollars), for the treatment.  So we ended up surrendering him to the vet so that he could receive treatment, and hopefully make a full recovery.  So a month or so goes by, and I decided to get another male for our female bunny to be paired with, so she wouldn’t seem quite so lonely.  Their initial meeting went much as it did with the other male, where she repeatedly mounted/humped him, though no real fighting.  He kept trying to get away and hide.  After a few intros, that behavior has stopped, and she even grooms him.  He however still seems very unsure of her.  He runs from her, and prefers keep his distance from her most of the time, and never grooms her.  Is it possible for one rabbit to be bonded, and the other not?  Will he come around in time? It has only been about a week, so I know not a whole lot of time has gone by, but the other two were completely bonded by this point, and I feel like the female (Luna) feels bonded with the male (Yoshi).  Yoshi came from a home where he was the only rabbit before, if that makes any difference.  Any advice?
