I just want to reiterate the idea of at least an EA. My wife was the last person on earth I thought would do it. Read Sandi thread, she was the same way. If you do find out she is, dont explode, dont say anything to her. Think on it, come to this board, have a plan.
Much of your story is similar to mine. I feel for you. Start DBing right now. The longer you wait and the more mistakes you make, the longer the whole process will take.
Good luck on your journery
