Destination wedding next year booked pre covid. All guests already booked. Not much we can do until closer to the time, most people still happy to come. DH had a phone call from his mum saying she feels terrible but wants to give us as much notice as poss that she isn't going to come. She feels at her age she's high risk and isn't willing to take the flight, she knows it's a while away yet but she's made her mind up. She isn't coming.
DH is devastated, but says to me straight away, quite matter of fact that we have to call the wedding off. I get it, it's awful that she can't come but it's her choice. We have over 30 over guests who have paid and will lose their deposits, we cannot cancel the whole thing because of one person even if it is his mum?
He's fuming that I don't agree. Help?
