Your husband may be narcisstic. Look at this website that is by Sam Vaknin, I believe...type in Narcissim in the browser and it normally pops up. there is lots of information and you can almost diagnose it yourself.
I believe you are in severe danger. Does your Mom know about all this? she lives next door?
He is NOT normal. You are in an ABUSIVE and DYSFUNCTIONAL relationship.
I am going to suggest that you do tell your Mom you are going to leave, so she will not worry, and you go to a woman's shelter. They can provide some guidance and support, along with a roof over your head.
People like you end up getting killed and disposed of, and your baby will suffer greatly.
Take care and keep this site posted on your situation. We do care.
