Can someone please knock some sense into me

Someone please tell me that I’m being an idiot and this is for the best.

Fiancé and I have saved up a decent amount of money, we got engaged last year. At first I started planning this big extravagant wedding, but the more I thought about it the more it gave me anxiety. We talked about it and we’ve decided it’s best if we use the money as a downpayment on a house, as we’re renting and have a 3 year old and have always wanted a home of our own, no matter how old or how small it is. He told me “a wedding is one day, our house would be our marriage”. And it makes sense, I honestly think I would regret spending all that money on a day. But I get a little sad thinking about not having it, we’ve decided to have a wedding/housewarming party once we’re settled in (hoping to buy a house the end of this year or early next year). We’re going to the courthouse this year to get married to make the home buying process easier, only telling close family, and then having a “wedding” party at the house. I’ve thought about taking a trip after we get married at the courthouse to make it feel more special, but I also feel like we shouldn’t as we’re trying to get new furniture and better things for the house, as well as an emergency fund. Can someone please knock some sense into me? I feel like an entitled brat and I don’t know what’s wrong with me.
