Bossy bunny, why has the bonding gone all wrong?

Question
Thank you so much for your help, but I felt there was no option but to take her back to the rescue centre at the weekend.  I'm pretty upset but it broke my heart to see Humphrey get bullied. He seems happier now but I still think he may like company.
I'm thinking of adopting a young doe (8-12 weeks old) from a breeder.  Is this a good idea? I'm thinking that if I brought her up myself I'll stand a better chance of a successful bond?  The rabbit I took back was difficult from the start (stamping feet, grunting, destructive), so would getting a youngster be easier? I understand that it takes time litter training a baby, but I don't mind hard work.
Thank you

-----Question-----
I have a neutered male rabbit, he'll be 2 in April.  I adopted a spayed female (Bess) 6 months ago, she's just turned 1 year old. She had a pretty poor start to life, as she was kept in a pet shop for most of her life before we brought her home.  I keep both as houserabbits.
The bonding process went brilliantly to begin with, she groomed him whenever he presented himself and they lived together seemingly very happily.  2 months ago it started to go wrong. She has always stamped her feet and make grunting type noises, but I put this down to probably always being scared at the pet shop she came from.  Now she stamps her feet and mounts Humphrey daily, emitting this wierd smell.  I thought this was her stating her dominance as Humphrey just lets her mount him.  I have also witnessed her eating his fur.  But in the last couple of weeks she has eaten all of his whiskers and is nipping his face, looks like she is searching for more whiskers. He now has a bare patch next to his nose, and is looking pretty miserable with himself.  I've had no choice but to separate them when we're not at home/at work.
I really don't want to take her back to the rescue centre, but I can't let this behavior get any worse either.  Humphrey is so daft that he just lets her do anything she wants to him.
What is she trying to do?  Is this relationship doomed?
Any help, most appreciative!
Regards, Samantha Garbutt

Sometimes changes in the home, and surroundings can bring about a break in the bond. Damage done is hard to reverse, because rabbit bonding is a hard thing to keep. Slight changes can ruin it. If this behavior has been going on for two months, I think that separating them for good is the best thing to do. Letting them run around to gether while under your supervison is ok, but she may harm him at night or while your gone.

Answer
I think you made a wise choice. Him being mistreated by a strange rabbit you brought in, may make him mistrust you. A young rabbit would be best, they are tougher to train, but you were correct about the boding. You will of course probably need to get her spayed, since she will come in heat and stuff, and have the agressive- not nearly as bad as the other doe, behaviors during this time and may try to breed your male. SHe will start becoming mature around 3 1/2 to 4 months. It is all up to you though.
