She must be seeing a lawyer...what now?

[Awoken]

This morning, W overslept for her job again. It's the second time ever. The first time, she had drank her to sleep and was too drunk to hear set the alarm. I presume it was the same this time.
She usually leaves around 5:30-6am. I get up at 6-6:30 to get the kids to school. This morning, when I got up I noticed that our dog (really her dog) that usually sleeps with W, was stuck in the hallway. I assumed that W had just forgot to let him downstairs before she left. Turns out he had slept in the hallway all night.

I'm making breakfast in the kitchen when she stomps in, cussing and angry about being late to work. I didn't say a word, and just got out of the way. 4 months ago this would've been a big 180 for me, since I'm always the one to step up and help her. She has said she resents this.

Still, I felt pretty hostile about doing nothing to help. I think it falls under NC, not pursuing, letting her have her consequences. But, I still doubt if it's the right direction.

I suppose it might have been better to cheerfully offer her help, get her coffee, ect...

I just don't know. Any thoughts?
