She's seems very selfish, a common trait in WW's. I wouldn't bother trying to understand her. Good things happen to people who work hard to make their life better, are you GAL? Are you improving as a person?
You need to refocus your train of thought on to yourself. Leave her be. In the simplest terms, she isn't your woman anymore. Act accordingly.
