Most married/divorced people regret the money they spent on their friends' and families' party you threw for them on your special day - especially the ones that got divorced. Don't waste the money- especially now.
Sadly there's money already being lost. I'm at least lucky to have kind vendors with good sense and the ability work with a reschedule. But even still, I am out hundreds of dollars for certain things that I paid for which I won't need later. I am fine with that, but not everyone can say the same. There are also other vendors out there who can't accommodate a reschedule and can't refund either, technically the contract is in their favor. That's what is making it hard for some couples to pull the plug immediately vs waiting it out to see what can be salvaged.
Money is not gonna bring grandma back...locking down the country is about saving lives. It's tough but it has to be done. You want a couple hundred people together, fine, have it in the middle of nowhere and stay there for 3 weeks. Let us know how many get sick, die, etc. See cruise ships.
On the bright side there is some correlation between how much your wedding cost and the divorce rate. Focus on what's important. The wedding is just a ceremony. My husband and I plan to share a nice quiet anniversary together on April 7th. We've been married 36 years and I will tell you although the wedding was fun I wouldn't trade those 36 years with this man for anything even if it meant not having a public wedding.
