I agree, Juju. I also wouldn't dig all through someone's email account if they accidentally left it open on my laptop.
I don't suspect him of being the cheater type. I think he's insecure because his wife cheated on him and being sick/unemployed is kind of emasculating. But it's funny you mention that, because the one time my ex-husband went through my phone call records on MY phone, it was because HE was having an affair and it must have suddenly occurred to him that I could do the same! lolol all he found was a call from the auto mechanic about my car being ready.
CMM is barking up the wrong tree because I am SO not susceptible anymore to anyone telling me what I should do! I actually have kind of a bad attitude - it's sort of "If you don't like the way I do/handle that, just get the F out!". I've cut him a lot of slack because of his precarious position and his illness but my patience is definitely wearing thin. Don't worry about me, I won't stand for more than I'm willing to handle.
