As Train said, it does sound an lot like your wife is in an A. Read through some of the other threads and the signs are all similar to yours. Is she protective of her cell phone? Does she dress/smell nice when she goes out or to yoga? Can you see her FB activity?
It is probably a good idea to do a bit of recon work to know what you are up against.
There are some great people here so you are in good hands.
