“Did I make the right choice by cutting my entire family off?”

Another soul answered...

Yes you did

Another soul answered...

It is your choice. No one else should validate or invalidate it. So you must be ok with your own choices.

It's often difficult to weigh the times where family did you good or bad. Sometimes, everyone is holding a match around the fire. This matter is not definitive, and time helps people realize whether a mistake has been made.
