It seems my spouse wants me to cover the wedding expenses

As the wedding approaches, stress is increasing. The other day, while discussing expenses with my spouse, they hinted that I should also contribute some of the money I’ve been saving for years. We normally try to be open about financial matters, but this felt a bit much for me. Because they had never mentioned anything like this regarding their own savings. Now I’m wondering if I should delve into the details and talk about it, or just act like I’ve misunderstood? What would you do?
