As a chronically late person myself, I almost feel I should apologize!

Let me bring up something that no one else has brought up, save Hank, but I've wondered from the beginning of the post...is something going on with your T? Something in her life that is making her "extra off". From what I remember of your posts, she's always been late and that bothers you. Then last week, she made the cryptic statement about being angry and was unkempt-looking. This week, she was (technically) on-time, but didn't remember the anger statement, your phone call, or that she was on vacation. She also changed your appointment time back to the original time, when you requested 10:30.

This sounds like someone with too many irons in the fire or in crisis herself. It would be good if you could consult with marriage T. If not, I would give her a couple more sessions to see if her aberrant behavior continues. That would also give you more time to make a decision whether or not to cut and run. I'm bad with decisions too, so I totally empathize with you there! Good luck with all this, Geez!
