IT really depends. I live quite a ways away from anyone I knew in HS or College, and it would be a legitimate excuse to not attend in person if I have to travel thousands of miles to get there, combined with not being very close to them.
I don’t know how I’d handle an invitation to a ‘gay wedding.’ Pretty sure I’d figure out a way to decline. I can only imagine someone related inviting us, and I don’t know anyone in either of our families who’s gay; our friendship circles don’t include any openly gay folks.
We didn’t have any of h.s. or college friends at our wedding. Just the way it worked out. We were LONG out of school, the wedding was on a holiday (New Year’s Eve), and we just didn’t send invitations to anyone who’d have to travel.
Our daughter and her friends travel across the country and halfway around the globe to attend friends’ weddings. It’s a totally different world. And, you can bet these millennials wouldn’t hesitate for one second to attend a ‘gay wedding.’
