.....another thought......unless your W is having significant mental health problems, and it doesn't sound like she is, SHE is probably well aware of the 6 month anniversary too. If I were you I would watch her carefully for any signs of HER reaction to this anniversary. You might be able to pick up some ideas of her state of mind in this regard.
If I recall correctly, you're a litigator, right? You probably know sneaky ways to elicit info from people without letting them know what you're doing right? (My sister is a litigator too. That's what she says she tries to do, although it helps if you have a willing witness I guess.)
