AITA for Not Attending My Brother’s Wedding Because of a Long-Standing Feud?

My brother (36M) and I (33M) have had a strained relationship since childhood. We've never seen eye to eye, and over the years, our differences only grew. We had a major falling out five years ago over some personal issues, and since then, we’ve barely spoken.

Now, he’s getting married and invited me to the wedding. While I’m happy for him, I feel that attending the wedding would be hypocritical since we haven’t reconciled. I declined the invitation, explaining that I didn’t want to cause any awkwardness on his big day. My decision has caused a stir in the family, with some saying I should put aside our differences for the occasion.

AITA for sticking to my decision?
