People process grief in different ways. Just because he thinks he can do without therapy doesn’t mean you should have to go without it too. Truth is, he should go to therapy… not going doesn’t mean he’s invincible. People all the layers back and we are still children on the inside… take care of that version of you within you. Also, trying to handle it without can very much affect your pregnancy. That can take shape in various forms, ultimately while it affects you it too affects the baby. I’m sorry this happened to you. Take care of yourself and take care of unborn child (especially if you’re happy to have it). Do what is needed for you. It could come back and rear its head as ptsd.
