First of all I know I'm not being too unreasonable to be incredibly hurt.
I have two siblings, one older one younger. A few years ago the older one turned 40 and the younger one suggested we'd get them an expensive birthday gift. It was something theyd wanted for a long time, so we both chipped in, got it and even had it delivered.
Today is my 40th. All I got so far is a text message from the younger sibling. Nothing yet from the older. I don't think they've gotten me anything. WWYD? Wait til the end of the day and then say something or never mention it. I'm so disappointed I feel like crying.. Its not the gift or the money obviously but the disregard 😞
