Saffie,
I understand what you are saying. My wife KNOWS what he did was wrong. She's already said she understands why his wife has treated him like that. She is NOT justifying it, I think she just feels his wife should have forgiven him after a point. My wife is a very giving nurturing person, and I think she is feeling compansionate and sorry for him because he's been pouring his heart out sobbing how bad he has it (which in fact he may, I don't know that for sure though.)
As far as the underwear, she picked them up at our house when she got my son from bus stop. I'm not home until 8:00pm and she gets home around 4:00pm
