Mr X,

Just some quick thoughts. And I'm just playing devils advocate here.
You said in a previous post that you weren't sure you want to know at this point. But obviously your gut is telling you 'something' is wrong. As a former BS I can tell you that 'not wanting to know' is an incredibly powerful fog mechanism that allows your brain somehow make sense of the crap the WS tells you.
Gets up at 4? Works out for an hour? Then leaves the gym to run for an hour? Hmm. How convenient that this is a time when you are definitely home, and can't leave! Has your wife always been an early riser?
