Hijack away - we're all in the brown stuff together!
I, like you, was very wary about calling it as a MLC. Like you, I see no obvious signs of depression (well, not now, but at the start) and she seems as if life is just dandy, but I think I've read on here that MLC'ers become very good at hiding the signs, and convince themselves that everything is OK, when it's not.
In my sitch, the most obvious sign is W having the tummy tuck and teeth whitening. Then there was the 'you're taking it out on me' speech when I went away with the kids, and they told her how much of a wonderful time they had and she just saw red.
Maybe it's how we, as either a LBS or sane spouse, are interpreting the signals is the problem and maybe, as we don't see out MLC'er that often (more in my case, as you are pulling off going dark well) that the outward signs being given are a smokescreen to hide the pain. Probably one for job/j3b/wonka to comment on having seen the other side of an MLC.
