Well one of my suspicions is now confirmed. The W doesn't pay any attention to how I look, what I do around the house, etc.

What does it mean when the W doesn't really look at you? Over a month ago I shaved off my full beard which I've had for years in exchange for a goatee. Last night I trimmed the goatee and a few hours later she looked at me and said "you shaved off your beard". I trimmed the goatee I said. Her response "when did you have a goatee?" How could this woman possibly see me everyday for a month and not noticed that I shaved? Co-workers noticed but she didn't? The isn't the first time I've noticed this behavior over the past few weeks either. A week after I replaced the mailbox she commented that she just got mail out of the new box for the first time. This was on Saturday after she got mail Monday thru Friday out of it. The other day she asked me how to open the trunk of my car. Something she has done at least a dozen times before.

Is this a sign of stress? MLC? Confusion? Could she have something medically wrong with her (brain tumor)?

Early October she is moving out so she can "think about what she really wants in life"
