TT, this is very common with WWs. When their LBS has in the past let them walk over them, when the LBS starts standing up for themselves the WW gets vitriolic. Here is the thing: after this is all said and done she may not like you very much, but she WILL respect you! Respect is paramount to being liked. Whether you ever R with her or not, whether you want to R with her or not. Standing up for yourself is important because being liked without any respect is not a great place to be with anyone.
Keep standing up for yourself. She may be mean and nasty and angry, but she will respect you.
