I was exactly you about 30 years ago. I really mean that, I understand about not wanting to be the centre of attention.
My then fiancé had automatically though of a church wedding, but as I never been religious I felt this was hypocritical. He was happy as long as he got a party
We compromised on a registry office wedding with about 30 guests (close friends and family), back to my mothers house for a buffet lunch, then carried on with a bbq in the garden and a lot of other friends arrived.
I wasn’t dreading it but I knew I’d have to go through the endless chats with everyone about how lovely I looked (I wore a very bright summer dress), all the gushing and social chitchat. I thought it’s would be embarrassing and cringey.
I was so wrong!! Everyone loves a wedding. You find yourself surrounded by people that have so much love for you, they are so happy for you that’s it’s actually a really uplifting experience. I didn’t feel a moment of cringe or embarrassment at all. In the evening when it was cooler, I changed out of my dress into some baggy chinos and a big sweater. Plus of course the champagne helped. But you are on a massive high all day.
I was the sort of introvert that wouldn’t take a turn at bowling when I found myself in a group who wanted to go. I’d rather sit it out. Another time we got the chance to go swimming on a hot day in someone’s private pool. Because I hadn’t shaved my legs that recently, I insisted on staying out and kept my trousers and t shirt on. I would get embarrassed just telling my boyfriend if I was on my period and god help me if he even got to see a box of tampons. I was an idiot. I tell you this because you can see that I was so self conscious that I wouldn’t try out anything new. There’s a thousand other examples I could give you.
So if someone as private as me can truly enjoy the love that just comes flowing and surrounding you on your wedding day, I think you should consider that you can enjoy it to.
By the way, the arrangements you have sound perfect.
