(I just looked back and saw that both your buns are fixed.)
I wanted to add that reading your experience was so similar to one of mine. But it my case it was my current girl who wouldn't accept the incoming male. I looked back and found the bonding journal I kept during that time. For 2 weeks I was working on bonding them. I did do some things differently than I had with any prior bunny bondings. I had never before done this, but this time I had begun swapping items from one cage to the other to 'mingle scents.' I also traded them in their cages too. I am convinced now that this was a very bad idea. I think this idea is fine for 2 bunnies that are already predisposed to get along. But for the two buns I had that were not, I think switching things only increased the territorial-ness and further aggravated my girl.
It is very upsetting and nerve-wrecking to watch 2 bunnies be aggressive. I watched the tension increase between the two buns with each bonding session (though it took awhile to realize it when one is always looking for any of those 'positive' signs). I so wanted it to work out, especially because the boy was such a sweetheart.
I do have the journal if you think reading it would help or give insight. It was during the 2 week separation time that was suggested by the rabbit rescue that I made a personal decision that I did not want to put myself nor the rabbits through further bonding attempts. It was a rescue I had a relationship with and they had no problem trading out that boy for another. Mocha, the replacement boy, won my Sapphire's heart and they are now quite the couple. For their bonding, I used the method from cottontails rescue (that I linked earlier).
I realize your girl is not from a rescue and is yours for keeps. In that case, my own opinion would be that it would be a good idea to separate the two of them for 2 full weeks before attempting the bonding again.
I sincerely hope you can have success after they've had time to forget. :goodluck
