stay strong. I know from what place you are talking, we have all been there. It does get better with time, it really does, but it does take months for it to be starting to turn.
In this situation our spouses turn into someone else, someone we've never met before.
I am not saying this to hurt your feelings or to project anything upon you, but you do have do protect yourself against the actions of your wife. Protect your heart and protect your financials, because your W just became an alien. Surely you have started wondering who is this person... She might come around, but it will take months if not years.
Hang in there buddy, we are all rooting for you...
