Help! Decision: Abroad wedding 10 days before mine

We live in Europe. My fiancé’s childhood friend — who got engaged many months after us and has many overlapping friends — decided to schedule his USA wedding less than two weeks before our destination wedding in Italy (Sept 2022). No problem in essence, right? It’s their wedding and we don’t have to go. But they just asked my fiancé to be in the wedding party and now he feels obligated. Plus his parents have been pressuring him to attend (although he isn’t close with him anymore).


Here’s the thing — I've never had COVID, to my knowledge. We’ve been engaged well over a year and Ive spent hundreds of hours in isolation planning our complex wedding in Italy meticulously. We’re expecting a lot of guests. Including people who have never been abroad — it’s a lot of responsibility.
What is the responsible thing to do here? It doesn’t feel right to travel so extremely (Europe to USA to Europe) one week before we have to travel to Italy for our own wedding. Honestly I don’t know how I’ll even manage to take off work for three weeks.
Plus, would my skin be a disaster in photos?
Anyway — what would you do?
