OP, I'm confused by your situation.
I don't want to sound judgemental about home education - it's true that, like all experienced teachers I have worked with lots of students who have been badly damaged by their parents attempts to H.E. , but equally I know it can work really well for some kids in some scenarios - for kids with some specific SEND for example it can be game-changing in a brilliant way.
But none of your posts really seem to explain why you and your husband have chosen H.E. for your children.
You do assert that many teachers don't care about the kids they are working with - is that your experience, honestly? I've worked in the profession for 30 years, and it's certainly not mine. A few teachers don't care about the kids much, for sure. But they are very much a minority - and as a parent you do have some ability to make decisions about who teaches your child.....
Yet, despite all the potential pitfalls of home ed for NT kids (around limited breadth of education and social isolation primarily); and despite the enormous damage it is clearly wreaking on your relationship, your own financial security, your mental wellbeing, quite frankly.... You still choose it?
Why? Why take this unusual, radical, risky course? If the reasons you choose it could be identified and dealt with, then your kids could go to school and live a more "normal" life and get a great, diverse education; you could go to work, be secure, confident, energised and happy; your marriage could thrive as you both contribute to it as equals and supported each other.... Etc
What is stopping you taking this very obvious course? You talked earlier about what your husband would and would not "allow". That worried me. I am wondering if there is something concerning going on. If so, please reach out for support OP. Both you and your children deserve a normal, happy life. Not whatever this is!
