Honestly, bonding can be a pain in the butt when it's a difficult bond. It can sometimes take months and be pretty stressful. I'm fairly experienced with rabbits and even I've decided that difficult bonds just aren't worth the stress, to me or the rabbits involved. For beginners, it's really probably best to try and find a match that is essentially 'love at first sight'. That means when the rabbits are first introduced to each other, they both seem very interested, relaxed, and happy with the other rabbit around, as opposed to acting quiet, nervous, aggressive, or indifferent.
When you do get that perfect bond, it really is nice to see how happy it can make your bun, snuggling, sharing their salad, mutual grooming. However, if you can't find that perfect match, sometimes it's better to let the rabbit just be single until(and if you can) find the right companion for them. Better to be single and a bit bored and lonely, than be matched up with a partner that they're stressed and miserable with
Probably the best way to go about it and see if you can find that perfect companion(or if your bun even wants one) is by finding a shelter/rescue that lets you try bunny dates with already spayed/neutered rabbits. Then you aren't committed to getting or keeping the potential companion unless it works out. Otherwise, in some cases when you have to commit and become the owner of the bunny first before trying a date, the bunnies don't end up getting along so then you are left with two single bunnies to care for instead of a happily bonded pair.
Just be aware that bringing in a new bun, or even just dates with potentials, can sometimes cause issues with litter training habits. It can sometimes lead to a surge of territorial marking at home. Plus there's also to consider the litter training of the new rabbit. I recently bonded in a new bun with my single girl bun, and being an older recently neutered boy bun, he's turned out to be a bit messy compared with her, leaving poop pellets pretty much everywhere he hops, though luckily his peeing in the litter box is a lot better than the beginning.
