Need Help handling affair thats still going on

[kjensen]

OK more news from our mutual friend mentionned above. My H told him he was pretty sure of his decision (D-ing me). He mentionned that tere is a 60 or 90 da window after you file where nothing happens-anyone know about this-is this a good thing? He asked if he could bring the OW on a camping trip to Moab with his faily that my H had been invited to(they said no-what is he thinking-we are married, our friend's kids will be there!!) H told both the friend and I that he had asked our girls if they wanted to go and they weren't too interested(he never mentionned Moab to the girls!).
Is it normal for the MLCer to create a web of lies for no reason?
Do they create their own warped reality and actually believe it?

Here's my [tentative]plan-please advise any and all:
I'm going to ask H to separate our bank accounts with me on Monday(goodbye savings-at least his portion!)
I'm going to ask that he works from his apartment-not our home.
I'm going to box up any belongings he's left here-so he can have them.
I will start separating our other accounts(put the electricity in my name/netflix etc)

Do you think this is too strong a move? Will it backfire and make him more attached to the OW? Is he still waffling and the D talk (to his friend-still no mention at all to me)is just a waffle and he'll change back soon? When do you know to take all of this seriously?
He still hasn't told his parents that we are separated. His OW recently divorced and I'm pretty sure she's giving him info on how to do it and what to expect...
