Is It Wrong That I Didn't Go To Their Wedding?

I had a friend who was a part of the close-knit group we had in undergrad. I knew her from high school. She graduated and ghosted me for a year and a half, then suddenly messaged me pleading to come to her wedding where she'd be getting married to my jerk of a voice teacher's older son, who would make eye contact with me at the gym and look away quickly after. So I let myself be petty and I ghosted her, choosing not to attend the wedding. Now I am beginning to think that I should have gone, not because I want to maintain the "friendship" I had with them, but because it may have avoided them all continuing to ignore me.
