...I arranged a month ago to go on holiday with my mum for the week. She's in a relationship but tells me she is trying to end it. I'm single with few friends so company on holiday is a treat. I booked and paid for the holiday - cottage by sea. Today she said she said she will miss the first 4 nights of the holiday to go away with her partner even though they are supposed to be separated. Feel so let down. Too late to get my money back. And not inclined to accommodate her turning up mid week. Now dreading holiday. Why are people so inconsiderate?
