Sorry, you are going through this. It really sounds like you need to figure out how to leave this man. I understand how you feel, his behaviour will make you go psycho. Its becoming dangerous if there is now physical violence.
Cocaine makes them paranoid, mine was the same, accusing me of cheating and hiding men in my house etc. That paranoia can turn to violence too, as he may believe his own delusions so much he could attack you.
If you feel like you can’t go on, then you don’t have to.
