As they say don't believe anything you hear in regards to MLCer.
Clearly he has a Lawyer who is advising him to go this route. It is amazing how easy a Lawyer can direct a MLCer to do just as your H is doing. They seem to need to be lead by anyone but you.
I would not email him anymore in regards to the divorce. I hope you have a lawyer and that he/she filed a counter claim with the court. If not, then do so now. Then I would have them file for temporary orders for child support, spousal support, etc. Go for broke. These need to be strong and in his face at this point to push him back on his a** and make him realize either work this out the reasonable way or the hard way. You have the upper hand if you respond immediately with a hard response. With 3 children at home you will have a commanding edge in this and his lawyer will line his pockets with your H's money while H looses.
