Oh god. Get out now. When I was around your age, I dated a guy who would say he didn’t think women should be able to get an abortion without the man approving, and then he pretended “not to have all the answers to that question” to placate me. He turned out to be a misogynistic abuser.

That being said, it’s understandable that you’d be confused and feel like shit. 5 years is a long time to be with someone and be emotionally attached. There’s nothing wrong with you for feeling awful about this. That makes you a normal human being. But what you need to do is protect yourself. It sounds like his worldview is becoming toxic. There’s a chance he could outgrow it if he puts in the emotional work to figure out what’s motivating his views...but I don’t think that’s something you should bank on.
