Cnut,
just keep the course. There is no magic pill. There is no right on wrong answer. There is no way this is going to be fixed overnight. If you want your marriage and you believe your W wants your marriage then you continue to do what you think is best for your marriage. Only you truly know what that is. You are the one there, hearing her words and watching her actions.
I get the "passion" thing she has for wanting to do the academy. My W has the same thing through paramedic school. Yes, I wish that passion was directed at me, but that's not realistic. I use to think so, then I realized that it's not all about me. She is an individual and has her own wants and needs.
I think when you said that the best thing to do is let her finish out the academy and then go from there was right on.
At that point you can go back to the OM transferring, etc
