My friend hadn't been on a sun holiday for a while and I booked an Airbnb in the canaries. She has her own bedroom and ensuite and as I was going to travel alone I didn't mind offering her the room for free.
I assumed we'd have meals together and agree on trips and have some alone time as well as hang out at the beach.
I know her over 20 years but not been on holiday with her.
She has a school friend who lives in gran Canaria who she met on day 2, day 3 and day 4 today, I don't really like her and so politely left after a couple of drinks on day 2.
My friend has continued to meet up with this friend and not see this as a problem. I'm absolutely floored that she would leave me alone to hang out with her when it wasn't discussed when I offered her the free room.
AIBU and what should I say?
