I think he needs to address his anger issues
and be nore understanding he got tou pregnant because he loves you he married you because he loves you.and pregnancy makes us crazy!!. now he needs to try to control himself a little more mine has severe anger problems as well and it can be so
trailing on our relationship.. but hes taken classes and gone to counseling to try to understand himself.. you know its not easy but I hope it gets better and he starts to see more clearly that's growing a life inside you is hard and it makes you do things and react ways you normally wouldnt ;)
You don't need to calm down. Ur growing a life and hormonal. He ends to understand what you are going through and be supportive. Also, he can't have those Anger issues with a baby:kid around. Sounds like you need to have a talk with him, or go to counseling if it doesnt get better. He needs to get himself under control! Good luck!
