work on the fb plan I provided you with, all this mention of gps info & tracking devices by your wife is her paranoia that you might have something like this in place already on her and she's trying to CHA (cover her ass). Haven't you noticed that she projects her thoughts on you about what she is actually doing but tries to turn it around as if you're the one doing it?
Turn the tables, have some fun with this. Don't discount jealousy and it's effect on a spouse, she's a cake eater right now, give her a slice of your cake but you enjoy it ;-)
