I'd just ignore the Instagram posts she's sending. There's no question there. In fact, I probably wouldn't even look at it, just clear the notification so that you aren't searching for a hidden message in there.
Glad to hear you're getting along better. Keep up the limited contact, and don't fall for any temp checks/small positive signs.

It is not things that bother us, but the stories we tell ourselves about things.
