My sister and I both live in Australia, though we’re originally from the UK. She’s in her thirties, engaged, with kids, and owns her home. Growing up, her relationship with our parents wasn’t great, and I’d say both sides were at fault. Now, I feel my sister can still be selfish and ungrateful. She holds grudges, especially against our parents. For example, when she asked our mum to babysit (when we all lived in the UK), and mum couldn’t make the trip, my sister never let it go and still often claims mum wasn’t supportive (because of it) - for context, our parents lived two hours away, and they’re low-income, so spontaneous travel wasn’t easy/affordable for them.
Our mum is generous and thoughtful. She loves finding pieces and sends clothes across for my sister’s kids, but my sister looks down on them because she assumes mum only bought them because they were possibly on sale. Last year my older sister claimed she didn’t have money to buy anyone presents (but bought her in laws expensive gifts) so I bought everyone gifts on her behalf.
On the other hand, my sister has been very supportive of me since I moved here. I currently live in her spare room, pay minimal rent, and she cooks dinner for me every night. So while she can be difficult towards our parents, she can also be caring towards me.
Recently, I offered to fly our mum and younger sibling over to visit us in October as a Christmas present. Before extending the invite, I asked my sister if she’d be okay hosting, and she nodded yes, so I went ahead and confirmed with our family. But tonight, when we discussed it again, my sister said she and her partner plan to return to the UK next year and won’t have any annual leave left to entertain our family, saying that I could just do it. When I pressed her on whether they’d still be around in October, she said they’re saving and would go whenever it’s most affordable. When I asked if she’d prefer our family not to come, she avoided giving me a straight answer.
I love my sister but on occasions like this, I can’t help but feel frustrated with her and feel negative about her as a person.
So AIBU for being annoyed? I’ve already invited our mum and sister, but now I feel like they aren’t welcome, and I’m unsure how to handle this with both my sister and our mum.
My sister also knows they can’t afford a hotel and that I most likely won’t be in a situation (flatshare) where I could put them up either.
