You seem to be giving up any kind of quality of life whatsoever for either of the adults in order to homeschool. You are bound to be knackered doing all you do, there’s at least 14 hours a day work there it seems? And he is working a job he hates to finance it. Is it really worth it?
if the kids went to school/nursery and you worked part time, and he switched to a less well paid but nicer job, your quality of life would be infinitely better
This is an insightful post.
What I got from your post is that you are both really resentful of the other. In particular your H seems to hate his job, and frankly his life overall and you too, if he hides away from you ( and the kids) every evening. It sounds like he has given up on parenting. He may feel quite isolated from the cosy bubble and relationship that you and the kids have ( they don’t settle for him etc). According to your posts, your husband has explicitly stated that he sees you as living the life you want, whilst he is living a life he hates to finance that. He’s deeply unhappy. You see him hiding away as a sign he is lucky to get a break. He will see it as a sign his life is so miserable, he needs to hide from it. So, for the love of God, do not present this to him as a benefit he gets and needs to give up for you.
You are also resentful and unhappy, feeling overburdened and supported. Thing is, arguing with your H for him to take on more, will go down like a bucket of shit given how he is feeling about you ( and probably family life overall).
You are in the most vulnerable position though, as he is the higher earner who has the financial ability to leave. ( I know a homeschooler to four whose partner walked out on them all).
You both need a proper chat from the starting position that you are both miserable and your life is not working for either of you. Something significant has to change to improve everyone’s experience of the quality of life of the family. Or the family may end up splitting.
