Your wife more than likely fired her lawyer because he/she was trying to advise her about what to expect and she didn't like the fact that he/she wasn't going to go along w/your wife's ideas....or...the lawyer advised her that she either get with the program or the lawyer would not take her on. Either way, we see this quite often in the MLC world, i.e., changing up of lawyers.
I would continue as you have been and stick w/your lawyer. You do not want to prolong this and she's in panic mode because she knows that the consequences of her actions are not going to be pretty. I agree w/Peace, she is definitely not done w/her MLC or the OM.
Continue moving forward and do not waffle on your decisions. She is hoping that by sending all of the texts, etc., you will waffle, feel sorry for her and drop the proceedings.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
