Hi
Shrug?
At least you thought so, as far as your side went.
Care? all of a sudden?
So, your being vague about it. I expect that the "teacher" has their own stuff to deal with. No time to deal.
As a coach/teacher, I have a life and have ghosted peeps before. Mostly because for whatever I want, as I do not charge money. If you thought there was a transaction that allowed you direct access for some reason, think again. If you had a paid relationship with certain specific expectations that were somehow made explicit and the teacher failed to deliver, then there is that.
Good luck,

I agree with everything D has said above. Teachers have their own stuff going on and are often wearing multiple hats, working full-time (sometimes very high-stress) jobs on top of teaching, etc, and so it's best to recognize that and not take it personally.

That said, I do understand the frustration of not knowing why the teacher broke off contact and the tendency to want to blame oneself for it. If it is really something you want to figure out, then perhaps a kindfully worded message through the correct channel, explaining your confusion, asking for some clarification, might be appropriate and helpful. But, it may not matter so much.

I have not been ghosted but have heard of it happening.  I have had a teacher tell me that they 'do not know how to help me', which I found a little bit strange at the time but in hindsight it seemed like the most compassionate thing that teacher could say in that situation. (They did also recommend a couple of other folks to me).

Best wishes
