Another clue that perhaps your editor isn't sabotaging your writing career, but she just can't love your book, is that she never says, "I absolutely love _______ (that part, or this character)!" According to bestselling vampire genre author, Anne Rice, try someone else! There will be someone who can love your books (characters, plot, ecetera) even without being prompted to tell you so. As for the other kind, your book would be better off with an author who would take it to a different editor. You wouldn't leave your kids, your pets, or your plants with someone who couldn't feed them while you were gone, water or nurture them - so don't leave your book there, with her.
I've had this experience, I hate to say. I had an editor who decided to take my only available computer file and chop out the 'fun' parts and the parts that caused readers to feel emotion about the topic, the plot, and the characters. That is a dead tree! That is not what an editor does. I rewrote the emotion, the fun, and the parts I thought I could salvage and published with Fae-tality Publishing.
