So your eldest is in year 6, if you move, you do sort of have to go now - as in the next few weeks as many areas the application deadline for secondary schools closes before the end of October and from what you’ve said about your old hometown, there aren’t many good school options.
when my dc1 was in year 5 there was a lot of people moving to be in the new location before school application dates, my dc2 is now in year 5 and the summer between 4&5 there has been 2 children leave and 2 new join her class. I expect more movement this year.
you really only have a few weeks to make the decision and go, is that what’s triggering the feeling?
mare you sure you’d be happy in the other location? It sounds like you’d have to move without a job, potentially lowering your/your dcs standard of living for a new career, you haven’t managed to make friends in your new town, but you have been there for years, are you sure it’ll all be easier in your old town?
If you stay to let your dcs have the better schools where you currently live, would it be a 9 year commitment to this town ? (Until dc2 finished year 11 and you can move for year 12/13).
