Put this in relationships because it's friendship related hope that's ok!
Just wanting general opinions about a situation. Going to try and keep this short.
We are a group of 6 friends, 2 of us from Europe and the rest from US. We met at an international conference a while back and have kept in touch via a WhatsApp group and have weekly video call- we've grown quite close and we just clicked as friends. There was our first in-person catch up organised earlier this month. All the US based ladies met up in Vegas for a long weekend (I couldn't make it).
One friend (friend A) asked if someone would be willing to pay for her at the time of booking and she'd pay them back (she was waiting for a work bonus). Anyways, a friend (friend B) advanced the money, they all went, had fun etc. After the trip, friend A ghosted us. She deleted WhatsApp, left the group, changed her entire mobile number (!!) and never paid back that other friend.
Now friend B was obviously annoyed but decided to chalk it up to experience and she won't be lending people money anymore. But just yesterday she said her dog has kidney disease and the vet prescribed expensive medication and she only has savings to cover a month of that medication. She had used some money from her savings to pay for friend A's Vegas share.
I know this doesn't really affect me directly but I am enraged at the situation. We found friend A on social media but no one can get in touch via phone since she changed her number. I want to do something but what can I realistically do here?? Am I letting it get to me too much? What would you do?
