why do you want to go dark? your sitch seems pretty fresh to me, going dark is recommended for abuse and toxic Rs. We all hurt during S, and going dark is sort of a step above the last resort technique.
How will going dark help your sitch right now? what do you mean final stages, it's been 2 months barely? I dont' want to downplay your hurt, for I've BTDT, thought he first 2-3 mths are the hardest that is hardly the end. He is very angry and hurt right now, in time he will calm down and perhaps will rethink this, you giving him the cold shoulder will just confirm your rejection. My suggestion? dont' do it, don't. Be the W he could be coming home to, I don't mean a Stepford wife, but find yourself again and be that confident person he fell in love with. No games, gimmics, sarcasm nor drama. A book that opened my eyes to what I was -unwittingly- doing to my M is "the proper care and feeding of Hs"
Dont' loose hope now, it might look hopeless but the good news is he wants to be involved with the kids, he is willing to come to the house, there are plenty of DB chances there.
Think of your kids, you have to be strong, you are here in this board to fight for your M, dont' give up without a fight, your H might be telling you it's over, forget it, well, they ALL say that, he has to have an excuse to leave (though I've read your old thread and it seems he had to go through a lot). Going dark is not giving this S a chance, you will seem cold if you try to minimize contact with him. Rethink what you are about to do.
