Think your wife is right - it sounds like you are spending far too much time & money on FS. You have identified the problems it is causing you with real flying, but you want to keep on doing it... Suggest you leave it alone at least until you are solo. I suspect you already know all the bits it can help you with inside out.
Instead.... There are the joys of air law, navigation, met, human factors, principles of flight and the rest to keep you busy. If you can't navigate a car without a GPS now is the time to start working on that. Ditto if a synoptic chart is meaningless.
