Our wifi password is actually on the back of our router. Plus we have it written in couple of other places when we have house guests so they can use it without digging on the back of the router. We don't know how it's set up in ops household and if they are both account holders

Op is afraid of her husband on a daily basis. I don't see how she can possibly demand he works in exchange for a daily password if she is scared to leave the house without his permission.

She said many times that she has to use savings to pay monthly bills because he pays none. She can't afford things. Cancelling things that are luxury is rational logical decision. If he starts getting mad calm response would be "I ran out of money this month. Could you please pay for cable and internet?" It wouldn't be a lie, she can't afford it. He either starts paying or they live without.
