You are not financially compatible.
You are not intellectually compatible.
You are not emotionally compatible.
He is emotionally abusive - silent treatment and using your trauma against you is despicable.
He's a leech.
He has DEBTS!! Urghhh red flags.
He will not be a good role model to raise your children.
If you don't end things and go on to have children with him, as a SAHD, he'll get custody, and you'll have to pay him child maintenance, and maybe even your house. Either way, as the non-resident parent and higher earner, you'll be worse off and bankrolling him still.
Please end things with him, he's really not a nice man. You are not compatible, and I'm sorry, but the other commenters are right, he's using you for your salary.
Please develop the ICK and end it. Don't forget to change the locks and remove your Applepay from his phone.
