My DS turns two soon, he's an only child & we're thrilled to bits with him. His Aunt's birthday is the day before his & this year, his little family tea party will be held that day, as it's a Sunday & the family are available etc. My DH has steamrolled ahead & invited the family round, effectively for a joint birthday celebration & its really pissed me off. I realise this probably harks back to my having to share, somewhat, my birthday growing up, every year with a sibling (we're not twins) & also due to the fact that DH's sister constantly requires his help for various reasons & I've had issues with how much time he's spent away from his own family doing shit for her. I should say, I genuinely like her, its more him than her insisting on doing stuff for her (although she'll ask too) & I think he feels a sense of responsibility for her, however she's made some pretty stupid decisions & has needed alot of support from her family through the years.
Anyway, I know it sounds stupid but AIBU to be pissed off? My own family will be there & I think it's weird having her birthday party with them, despite it being on the day of her actual birthday. More annoyed DH just went ahead & put it out there without asking me. Having re-read this I know it sounds ridiculous yet I'm severely pissed off. Told DH that I would not welcome any more joint celebrations in the future. Am I being unreasonable??
