I have one sibling, a sister, who is lovely and I have a good relationship with her. She's a few years younger than me and probably been mollycoddled a bit as a result (including by me). She has a heart of gold but sometimes she seems to be very focussed on herself and not so much when I want her to be around for something. If she has something going on she goes on and on and expects me to be there, as I would want to be as her sister, including a week away for her hen do even though I have young DC and always being out to celebrate her birthday and a recent award she received. When it's my birthday she posts a card to me but doesn't visit, usually has plans the weekend of my birthday (she's been away the past three years) and it has stung. I always buy a thoughtful gift and visit her to give it plus I know when her birthday is so I tend to keep that weekend free as I know she likes me to join in her celebrations whether it's with her friends or our family.
She just told me she can't attend my hen do in May as she's made other plans. She knew when it was as I told her but she's booked a holiday. I was really upset because I thought she'd see it as a priority. It's not a cost issue, and I don't think she did it on purpose, it's as if she just didn't think of it. She didn't even call to let me know, she only told me as I told her my MOH hadn't heard back from her. I told her I do so much for her and I'm always there but recently it seems it's a one way thing. She got annoyed and hung up the phone (but I think she was upset rather than being deliberately rude) and now I feel bad.
I want to say sorry for having a go but I also still feel let down and I expect if I apologise she won't think about what I've said.
To be clear I don't begrudge her making other plans. It's because it's clearly important to her that we're there when she has something going on and I always am but now it's the third time in a few months where I feel let down by something like this.
I suspect I probably am being unreasonable because I shouldn't expect her to be there if she doesn't want to be but then I should have given less to her. She's my only sister so I just don't know.
We are in our 30s before someone says we sound like kids!
