Thank you everyone for your advice. I have so much dread and anxiety about what this will do to my kids.
My husband does seem to be moving quickly (at least to me). I think he is trying to run away from all of the bad feelings inside of him as fast as he can. I think he believes that as soon as he is gone everything will be better for him.
I am waiting to see if he follows through on his aggressive time table. Historically, planning ahead and coordinating a major life event (like moving) has never been his strong suit. Who knows about this new MLC person though.
