Light Switch, Be sure to talk to your attorney about not moving out. You don't want to be able for her turn it around and say that you abandoned your family. I know someone this happened to, she kicked him our more or less and then told everyone he left her.
Also be careful of selling any marital assets(camper) at this time.
And by the way buying new clothes is not girly, it's hot! It might even make her jealous thinking you are trying to impress someone else!
Life's challenges are not supposed to paralyze you, they're supposed to help you discover who you are. -- Bernice Johnson Reagon
