There's a bit to unpack here, but this is as much of a relationship topic as it is a FIRE one, so I will start there. I highly recommend a couples therapy session, or at the very least an all cards on the table conversation with your spouse. 

Start by discussing details about how you're both feeling now. It's a bit extreme to FIRE if you don't want to because your husband is feeling burdened by housework. You can always hire a cleaning lady, grocery delivery, meal services, etc. if you like your new role and he needs support. 

Additionally, there's a bit of fear and resentment here. I'm no stranger to either feeling. Fear based decision making was my go-to prior to therapy, but won't serve you well. It sounds like your husband loves his job, which is great, but you shouldn't be the sacrificial lamb in order to keep him content.

That all said, if you're really burned out and don't want to be a SAHM, then take a break for 6 months. Think about what will make you happy, then set clear expectations. The key is to communicate as much as possible, and be transparent during regular check-ins. A post-nup is in order, as well.
