I refused to meet up for the very reason you mentioned. I really tried not to be inflammatory. I just said 'all the things you wanted to discuss we can discuss over email or at the family dispute resolution'. Initially, it was just about our son's mental health issues but it has now turned into everything, including that the kids want to live with her, that I'm neglecting them, that they dont want to be near me, that they just want their mum, etc...and her saying that we need to meet in order to discuss it.
You are right about not replying and being careful when I do reply. I reply as if everything could potentially read in court. I don't engage in the 'but the kids want to live with me' conversation. I really do try to keep it relevant. I replied selectively to several of the emails from last night and today with 'I won't discuss any of the issues you've raised except at the family law conference you initiated - please let your lawyer know a date when you're available to do this'. I actually read through all the responses I got on this thread to keep it calm and impersonal.
I thought that maybe the swing from telling me to communicate only with her lawyer and being gung-ho about the mediation to now not even wanting to go to mediation or involve lawyers may have been an indication that legal aid told her that she doesn't have a good case. It's not that she doesn't want consent orders, it's just that we currently have orders that I think a court would be reluctant to change (and that she doesn't like) because she would struggle to meet the threshhold of rice and asplund.
Basically, nothing has changed in our circumstances except she wants the kids to live with her full time and then relocate with them. I think she maybe thought she had a strong legal case and is now realising that she doesn't and so is saying 'well we don't even need to worry about orders, let's just act outside of them for the sake of the kids and let them come and live with me'. Does that make sense?
