It has been my experience with Labs that we have had over the years, that they make excellent family pets and are highly intelligent. Is it possible that you feel nervous about dogs, in general? We had a Golden Retriever/Aussie mix, loved everyone he ever met, he never showed any aggression until my son's girlfriend started spending time at our house. It wasn't instant aggression, but developed over time. She was never around dogs growing up and had a bit of fear of the unknown and after a time of her being mis-trusting of the dog, he became mis-trusting of her. She would try to 'rush' by him to avoid contact and he we then bark at her. It was the strangest thing, this dog literally treated every stranger like his bestest friend, but he never did bond with her.
There are some really good ideas under the "Behaviour Training - Online" section that may help, such as, when she jumps up on you, try turning away from her and even walking away, but when she is calm, get her to sit, give her a pat and a treat. Find instances of good behaviour where you can reward her and hopefully a bond will develop with you as well.
I hope that this all works out ok for you.
