Your W has gone full psycho. Same as mine. You have a good lawyer that is a top priority here. Make sure you keep every email and text. Make a journal and take notes of everything. Short, concise, factual notes. It sounds to me like W may be luring you into an even worse situation here. Be careful. With a good lawyer, this will pass and you will get to see your babies as you are entitled to by law.
Take care and hang in there.
