You seem to me to be a real human, contemplating real thoughts about life.
The thread you which you started, "Establishing a Life of Meaning", seems real.
And the post you added to the "Parenting In The Simulation Age", also seems real.
But please understand - the jaded folks here have spent decades proving stories fake.
For you to understand the perspective of folks here, you need to ponder all the threads.
This will take years or decades of quietly reading through each page of the 1000 threads.
To begin to understand that nobody was killed on 9/11, you need to read Simon's intro link.
At the very least, you should watch Simon's 19 videos which are currently hosted on this page.
First realize how thousands of fake "victims" were simulated to start wars, that is the first step.
Then realize that all the media-pushed "victims" are simulated, all of the "terror" stories are fake.
Then realize all of the "Nuclear Bomb" stories and "Humans in Space" stories are equally totally fake.
Your kids must memorize all the official stories (to get money) AND your kids must also learn the truth.
See, no need to choose between "teaching them the official stories OR the truth" you need to teach both.
You are lucky to have a relatively-rich husband ("who formerly worked at NASA") financially supporting you.
Enjoy his money (which he received for helping knowingly/unknowingly prop-up the "Humans in Space" fraud.)
Enjoy your lucky free-time at home (which he pays for with his current mainstream job, whatever that may be.)
Enjoy your lucky life which most would LOVE: someone paying for your organic food and your home-schooling gig.
I recommend you carefully watch the 19 videos (by Simon, the creator of this site) in the order shown on that page.
And I recommend you carefully read through the threads here for 100s/1000s of hours before posting more. Learn 1st.

PS - while learning how to notice the illogic in all the official stories [lies], "photos" [images], and "videos" [animations],
over the next 100s/1000s of hours reading through the threads, I also recommend some appropriately real mellow music.
Summary - Yes, you seem to have already intelligently realized: the official stories (even in "history" & "science") are lies.
You are experiencing rational feelings about that grand realization and about a spouse who doesn't admit/know the truth.
Your thoughts seem intelligent, rational & compassionate, and you seem to be doing your best to teach your children well.
In addition to teaching them the official stories to pass the official tests, teach them to notice lies using Logic and Analysis.
Gradually, after reading enough of the past decade of posts here, you can gain the perspective to be a contributing member.
Relax, remain centered & happy by keeping your awareness (not worried about futures) firmly aware of each Present Moment.
