Your situation sounds like it is emotionally grueling and honestly I don't know what to say.
As you know, we all hear one side of the story here, our side. And I am sure if we spoke to the WAS, we would hear a totally different view of the situation.
In fact, I recently spoke to one of the WAS's of a poster here, and heard a completely different story, so opposite in fact that it was mind boggling!!
If your wife is indeed having a crisis of sorts, then you have alot of work to do, and with that comes an abundance of patience.
She does sound like an incredibly spoiled Princess, who is used to having things done her way, and I guess that is what irks me about some of the things you have described.
Have you always catered to her needs?
What happens when you say "NO".
What are some of the things she has complained about concerning you during the Marriage?
Have you read the Taming of the Shrew? (Just kidding) (((((((hugs)))))))
There can be no testimony without a test. I am praying to go through this test and come out the other end with a new and better marriage then before.
