This happened to me too. At one time I like the AB series enough to buy Obsidian Butterfly in hardcover, and my short list of novelists to buy in HC is about five these days. Not only have I not bought anything new in a long time, I sold back my earlier ABs to the used book store because I knew I would never reread them knowing what the Anitaverse turned into. About to sell back my MGs as well: because Mistral's Kiss had no plot. I only started reading MG because it was supposedly a story arc of six.
