She’s not a nice person. Self serving, rude and a smartarse. Think deeper about who you stand up for.
She has said multiple times in posts/podcasts/stories that she left in March and had a return ticket for May for a friends wedding. She - like many others, myself included - thought the pandemic was a blip, maybe for a month or so. I don't think anybody foresaw how Covid changed the world with lockdowns/travel/quarantines etc.
You would swear she left with a one way ticket never to return the way you've described it.
