If you’re the one working then why would your SO be able to threaten to not pay bills? Maybe it’s time to change which account your paychecks are going to. Have you considered opening a separate account just for you? Or try taking your name (or theirs) off as many joint accounts as possible. Maybe freezing your credit so nothing else can be opened in your name (assuming you’re in the us)? Are you are legally married to them? If so filing for divorce might be another avenue to talk to a lawyer about. (Most lawyers don’t charge for the initial consultation).

Are there any domestic violence shelters in your vicinity? It truely sounds like you’re in an abusive relationship and being held hostage in your own home. It’s only a matter of time before the violence gradually increases, because nothing you will ever do will appease them long enough to change their minds on how to treat you. Can you record people in your state/country? The us has some states where only one party needs permission to record so giving yourself permission is fully acceptable to begin recording. There are also some apps that can record audio/video when the phone appears off and uploads the video onto the internet.

You do not have to answer any of these questions. This internet stranger is just worried for you and truly hopes you find a safe haven. Regardless of anything else, I’m proud of you for working so hard to better yourself and your circumstances!
