I've been with DP for over 10 years and we have a child together. Over the years we've been together I've received Christmas presents from DP's parents but never a birthday present. For Christmas I'll receive something small like socks or chocolates and just a card for my birthday.
My DP's brother is currently in a relationship with another man who has just posted a thank you to my PILs for his birthday present. They have been together less than a year. I'm aware that DP's sisters ex partner also received at least one birthday present from them during their relationship.
AIBU to feel a bit upset by this? It's not about the actual lack of present but rather the meaning behind it.
