Time to file? (Thanks BenB - part 2)

Texted W this morning that pre-school teacher reminded about our schedule (she doesn't always fill in her times and I used to handle that mostly).

She answers with "OK (smiley face). I am not used to this new routine yet".
So not taking responsibility. I haven't answered.

Also still hurts a bit when she uses those phrases. I brush it off easily though.
Anyway this whole answer makes me think that she STILL thinks the status quo is OK and will keep going, and that there is NO disagreement or any concern now.
As if I am fine with everything...
I guess I shouldnt but this gives me an urge to tell her its not fine, she has TOTALLY deceived me and I will NOT be helping/catering/comforting her anymore...
