Update:

I had my son this past W/E and we decided to travel to visit grandparents 300 miles away. My XW offered me her car for the trip since it gets twice the gas mileage as my truck.

When I returned the car, I left a note on the seat that said "thank you". She called to tell me your welcome.

Last night when she came by my house to pick up son, she was visibly disturbed. I asked if she was ok. She said "my life sucks, I hate it and I can't take it anymore." I said I'm here if you need to talk.

I guess it wasn't just me making her unhappy....go figure.
