How do I call off an arranged marriage?

So my family set this up with someone from back home — seemed fine at first, polite, good job, the whole thing. We’ve been talking for months, even met up twice in Dubai. But the more I get to know him, the more I realize we’re on totally different pages. Like, I’m kinda liberal, I work in design, I drink sometimes — not a big deal to me. But he straight up told me he wouldn’t let his wife have a career after kids. Not even part-time. And he expects me to wear a hijab even in London, which I’ve never done. I tried brushing it off at first, thought maybe he’d change or we could compromise. But he’s super firm — says these are his values and they’re not up for debate. That’s when it hit me: this isn’t just cultural differences, it’s fundamental stuff. I can’t imagine being with someone who sees me like that. tbh I feel kinda guilty because my parents are so invested. They keep talking about the wedding like it’s already happening. But I can’t do this — not for them. ngl, I’m scared to tell him it’s off. Anybody been through something like this? How’d you handle it? — I just want to be with someone who sees me as an equal, you know?
