Sorry to hear this. Accept that you can not change her, only you. If you love her, support her, even if you disagree.
As far as the children, I hope you dug down into the quotes thread and read some of the past discussions. As job said, let wife do all the heavy lifting. Think really hard if you want to use the "we decided" path or the "Mom decided" path... IE wife says "I have decided to move out".
Best thing you can do is embrace the master bedroom as your new greatest space. Be supper excited that you can now make it the way you want it. Make in manly. For example: Paint the walls black. Put in red mood lighting. Pictures of airplanes or cars or battleships. Theme it out. Go get some manly bedding that compliments the look you are going for. It should be something YOU really like. If she questions you, a simple "I like it" or "I decided this looks better" etc.
