Dreaming of being st SAHM but my husband does not want me to

First of all let me say I love my husband more than anything. I’m not complaining about him just searching for advice or insight. I’m a teacher and I really am not that passionate about it anymore. I teach first grade. I work 8-4 sometimes 4:30. I feel like a bad teacher because I try to leave as close to 4 as I can despite not being ready for the next day or emailing parents. On the flip side I feel like a bad wife and mom because I see my LO (soon this will apply to 2 kids when I go back from maternity leave in May) for like 30 minutes in the morning as I rush her out of the door then 2.5 hours at night for dinner at 5:30 then bedtime is at 7. So I feel like I’m an inadequate teacher and mom. I have asked my husband if I could stay home time after time but it always ends up the same: my insurance is too good, he’s worried I won’t go back after a leave of absence (usually 2 years), and I’ll want to end up wanting to home school (which I have no desire to do at all or have even expressed a desire). At this point with two daycare bills I only contribute $500 a MONTH to our income plus insurance. Our discussions always end up with me crying and him saying I’m too emotional to make a decision like this. A few times he has just said “fine stay home.” But now I feel like whenever he agrees he isn’t supportive which will lead to a resentful situation. So I’m just feeling hurt that he doesn’t *want* me to be a stay at home mom. I see it work for other families and it makes me jealous (not proud to say that). He says since his mom worked its a foreign concept to him. He also says “I want to be with the kids too” but he is the bread winner by far. We would be fine financially. I just feel so bad after we talk every time and I feel bad he doesn’t want me to do this. any advice? I’m so tired of crying my eyes out at the thought of *never* being a SAHM :(

Thanks ❤️

*UPDATE* so we looked at the numbers and we could make it work BUT his insurance is SO bad. So much worse than I could have imagined 😩 today I’m going to talk to my old coordinator about becoming a part time teacher so we can keep my insurance, my kids are stay with their friends at daycare (and it’s Spanish immersion so she can continue to learn Spanish, but then would get 2.5 more days a week with my kiddos! So please say a prayer for me 🙏🏽 Also, I just have to say I got my husband’s feelings all wrong. He is so supportive of this- I am so humbled by his love. Thank you all for your support and advice ❤️
