Scott, unless the LBH is willing to just let her have whatever she asks for, these things always have a way of turning ugly. I am sure she is being a bit conniving and manipulative with the mixed messages: Do not ask me questions directly in the mediation sessions, but oh come celebrate Easter and birthday as a family! WWs in particular are masters at playing with the LBH's heads. In my sitch my WW would talk about having friends over later that year, and then the next was talking about looking at apartments. It is surreal. Gaslighting. Just plain confusing.
