Husband doesnt want baby

I'm not sure what to do here. My husband and I have been together for 10 years. We have 2 kids. I just found out I am pregnant with our 3rd. When I told him he was shocked but happy. That was 2 days ago. Today he's telling me that I sexually assaulted him by entrapping him and getting pregnant by MY choice. That it is a form of rape because I said I didn't take my birth control at the same time a couple times but never missed it entirely. He's saying he's been all over Reddit and everyone on there says this is grounds for divorce and that he's not happy. So I said then divorce me or set up a time for an abortion in a different state (we live in OK). He starts freaking out saying that if he did that I would use it against him in every argument from here on out that "he forced me to have an abortion and kill our child". I told him I did not do anything on purpose and am just as stressed about it as he is. I work full time and he is in medical school. But if he wants to divorce then he needs to just leave. Right before this conversation he was telling me "how I was going to leave him and take all his money after he becomes a doctor" and would not stop about it. I told him to just stop that I'm not leaving him. Then he said that "he's telling me and is going to KEEP telling me so that when it happens he can throw it in my face that he KNEW it was going to happen and that he can tell our boys that mommy is just like all women and left him and took his money." Like I feel like I can't do anything here.
