Need to cancel 5 weeks out - concerned about financial impact on guests

6 months ago, my gut told me to call the wedding off after I stumbled upon my fiancé sexting other women. I chose to forgive what I thought was a one-off mistake.

We’ve had an open phone policy since then and a few nights ago, I was anxious and poked around. There was a message thread dating back to 2023, the year we got engaged and a year before this alleged one-off incident occurred. 🙃

Turns out it’s even worse than that. We started dating in 2018, and he finally came clean that this had been going on and off from 2019-2024. (Who knows if that’s even true).

Absolutely not.

Anyway. Had I known that 6 months ago, I would’ve canceled the wedding then and saved myself a lot of heartache. But here we are - 5 weeks out. Flights were extremely expensive due to a large event happening in the city we live in, and it’s inevitable that some guests will lose money from having to cancel flights/accommodations.

I really, really don’t want to inconvenience my guests. My (ex?) fiancé is a high earner and wouldn’t be ruined if he reimbursed people financially impacted by his actions. I know this is unconventional, but I’ve given up y’all.

Curious to hear your thoughts. The thought of burdening my guests is really making me hesitant to cancel the wedding. I don’t care about the lost deposits.
