My brother is getting married sometime but don't know exactly when. My older brother already had his wedding three years ago,but I wasn't in his wedding at all.

I have seen where siblings can be in their siblings wedding even though it's the bride choice to choose who ever. I just feel like an burden because all I wanted to do is be in at least one of my brothers wedding for an memory someday to look back on.

Also are you supposed to do an renewal vows at 10 years of marriage?
