The internet is a difficult place to ask for advice as mostly people have very little to offer but their own opinion. So I will say that my wife is a Dr of Psychology, we have 30 years together. Plus, at one point in my life I was a professional interrogator, so I do have an intimate understanding of how people think.

Because your husband does not think as most people do, he is with little doubt a paranoid narcissist
. Ergo, the only entity he cares for is himself.
This link maybe useful to you for some research:
As might this:
The basic bottom line is that he has a mental outlook which in truth has no 'cure'. He sees nothing wrong with what he does as long as his needs are met.
Confrontation absolutely does not work with such people. To interrogate such personalities you praise their intelligence and let them talk ... because they are their own favourite subject.
If you want to see a paranoid narcissist in action then just look at Trump. Because he is one. Trump is a man who had Time and Forbes magazine covers faked lauding himself as a genius businessman .... which he then has hung in pride of place in his hotels.
If Shay104 you want a 'normal' relationship, then your husband is I would surmise not able to provide that; Not how he thinks or sees the world.
Unfortunately through no fault of your own, you find yourself in a difficult position. Therefore my actual advice is that you, without informing anyone else especially your husband
, is get to see a professional psychological counsellor or maybe talk to one on the phone.
Because you need someone who understands your husband's condition, so they can help you through the complex maze which that extracting yourself from your marriage may well present.
