Hi SN, You seem to have a good handle on things with all the reading( I did the same thing!). I wouldn't be the one to move out. Stay in your home and take care of your kids.
Remember she is not the person you married-people describing MLC as an alien invasion seem to have hit it on the head. Different behaviors and the things come out of her mouth will have you wondering just who she is! She's figuring it out the hard way(on everyone!). She, hopefully, will come back and be the woman you loved and wanted to spend your life with, but its going to take time and its not a pleasant ride.
Focus on YOU and your kids. Hang in there. Visit often and vent here(not family/friends).
