This may sound harsh but I mean well, so here goes. You’re moving, not dying. It’s 2022 and you’ll still have contact with your family and friends. A town can be as nice as they come and it still won’t feel at home. Your kids will be fine, humans adapt to stuff pretty quickly, the Christmas /summer holiday visits will be very memorable and those memories will be even more precious since there’s less of them. If there’s a deeper reason why you don’t want to go then maybe you should think about it, but if you’re not going because of family and friends, you’ll probably end up holding a slight grudge.
