I have to reply to your statement that you are not smart, but just a housewife (paraphrasing here) and can't talk work with him (why would he want to after working 12 or so hours a day at it? Seriously, after work that is the last thing I'd want to do)
The smartest person I ever knew was a SAHM with a 7th grade education. She was married to an electrical engineer and she ran circles around him in regards to being a smart cookie. (she was my Mum). She taught me to read at age 3, she taught me long division after my Dad failed to make it click. She taught me fractions while cooking - She may not have had a degree but she was in some ways, smarter than I'll ever be.
Like her, You ARE EXCEPTIONAL. Remember that!
You run your household, which requires managerial and organizational skills.
You handle logistics of getting everyone where they need to be, on time and back home safe and sound. That takes navigational and organizational skills.
You probably pay bills and balance your check book - that takes math skills
You cook healthy dinners - that is an exceptional skill to have in this day and time.
You listen to your kids when they have problems, offer up advice (and I bet that is not limited to just your kids)...so you are an unpaid therapist for lack of a better definition.
One of my best employees was a middle aged, going back to work SAHM. Know what sold her to us? The fact she had all of the above skills and was honest.
Please do not think that you have nothing to offer in way of conversation. You have more than the AP, and honesty to boot.
Hang in there, you have all the time in the world to make your decision on what to do.
Please tell the OBS though.
