Ready for some forum help

[NewB3]

Tonight I came home and had picked up Chinese. I figured I would get home before them. She commented that I did not call, I said I thought I would arrive before them. She ate and enjoyed. Looked exhausted. She is not sleeping well, I know Mondays couples therapy is weighing heavy. I simply said, you look tired. She said yes and that she had attempted a nap at lunch, but slept maybe 5 minutes. I told her I would take over with S3.5 for the night. I told her I knew being tired made her job tough, but she can get some rest tonight. "I know it is hard to function with little sleep"
Later I told her goodnight from the bedroom door. Told her thank you for being a good mom.
Interactions are weird. Detaching, but feeling the need to stil be the guy she would be a fool to leave...compliments, help with anything, dinners, etc.
