Well, it's your call. There is absolutely nothing wrong in admitting that you cannot do what would need to be done to get Tam and Pixie to get along. If it doesn't feel right for you, then it's not right for you.
But in the end, I think too many people think of their dogs are people, with human emotions, when they are simply dogs. Doesn't matter the breed, sex, or upbringing. Even the most ferocious dog, or frightened dog, or stubborn dog can be trained. Give or withold food, they will obey very quickly. I know it may seem cruel, but dogs really don't have the same type of feeling we do. They need to be consistently conditioned. It may be a lot of stress for the humans, but believe me, Tam and Pixie won't dwell on it like we do.
And yes, it is very difficult to say no to a cute face. MoMo has mastered it, but I remain strong. (mostly.)
And your situation is actually very common. I know it won't make you feel any better, but it's just the nature of dogs, as much as we may like to think they are far removed from wolves, they still have common behaviors.
I know you trust your breeder, but it might help in the future (don't give up, you'll get another chance later) to consult an experienced dog trainer or behaviorist (not a pet psychic) help out. Dogs, like wolves, left to their own devices will fight for position in the pack. It is in their nature. It is up to us to tell them where their position is in the pack.
