I might be wrong, but I think your wife is just a confused individual right now. If she has a lawyer, she may not be telling him/her everything, i.e., degree, etc. Eight years isn't all that long to be out of the work force. She better start looking and soon as a judge would advise her to get her ducks in a row and plan out how she's planning to support herself once a divorce goes through.
Stay the course. I think you are doing fine.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
