I feel disgusted by the amount of spending my friend has done to have a wedding.
Why does it matter to you how much she is spending at her wedding?
I feel like I'd be wasting so many paychecks if I was paying for this event.
I don't think you should worry so much. You should spend your money however you please at your wedding. It is her special day and she wants to remember it always.
I'm going to save my money and have a small wedding when I get married. I don't need to impress anyone.
You don't have to waste excess money on your wedding. You're allowed to do whatever you want because it's your special day.
