Whatever option works for each of us, it is important we find ourselves satisfied with our decisions.

This is very true. And we don't just decide blindly.

One of my students was so surprised, and couldn't understand, how I would not miss teaching and the students

I think your student must know how much you are very passionate about teaching and piano and that you having some doubts about moving means you truly are happy with where you are right now, doing what you love and thriving too.❤️

Cheers to you and thank you lots too :)
