Great job GAL, Ghost! If you can detach your feelings of paranoia from your W's GAL, you will make some progress.
She has gone out before, and as far as you know.....nothing significant happened. So try to relax and not think about all the "what ifs". Try to keep busy during the time she's out.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
