I am sorry to read that your situation has taken a turn for the worse. I am proud of you however for sticking to your ethical principles. I will always be inspired by you.
I am in the same boat although my wife now refuses to negotiate our divorce mediation. Our only communication is through email now. I am unsure what to do next. I will have to contact an attorney I guess. Until then, I will keep on keeping on. What else can we all do?
