AIBU to be upset over not being mentioned.

[catsarebetter]

Ok, not the most serious thing in the world but just wanted peoples thoughts on whether I am being over sensitive.
My brother lives 2.5 hours away from the rest of the family. He has a one child, I have 3, so when he comes to visit (which he hasn't for ages because of lockdowns) he always stays with my parents who are 10 minutes up the road from me. We don't tend to go and visit him as it would mean a hotel stay or going there and back all in one day.
He has just told my mum that he's coming up in August for 3 days, which is when me, DH and DC are on holiday, my mum knew this but didn't think it was worth telling him. We always all get together whenever he comes up and normally they all come to mine for a big meal. I thought it might be relevant that I wasn't around but my mum just very bluntly put it "well you can't see him them because you're away". My brother doesn't seem very bothered that we're not here either.
It just makes me feel like I'm not very important to them, that really he's just coming to see my parents but if I'm on hand to provide a meal then great but if I'm not, then never mind. I burst into tears when I came off the phone from my mum, then started to question whether I should be upset.
What do you think?

It's good for your brother to see his parents without you there. I also think it's fine that he wants to see his parents more than wanting to see you.

If you cared about seeing your brother you'd see him more. Perhaps this is your cue to make more than an effort. 2.5 hours each way doesn't require a hotel stay if you leave nice and early.

Wipe you tears away and realise that this was bad luck. Imagine how your brother would feel if she'd said don't come because OP is away. That would be shit for for everyone. You get to see your parents regularly - don't spoil things with your FOMO

It’s unreasonable to expect him to change a date which is convenient for the guests and hosts. It’s unfortunate that you’re on holiday but you can travel the 2.5 hours (it’s really not that far) or get a hotel to visit him. If you hardly ever visit I expect he thinks you’re not that bothered and will just see him if he’s around

Your parents are 10mins up the road from you. Your brother who lives 2.5hrs away usually comes to stay at your parents....but you can't be bothered with the 10min journey to your parents to see him? did I read that correctly or has OP made an error?

Your op says you don't tend to visit him. Follow up post says you do but not as much as he comes to visit. Then you see him twice a year. So which is it? Do you visit or not? When did you last do the travelling?
Given that he is the one doing the travelling then surely he has to do this when he is able? Do you not speak on the phone for him to mention when he's coming or for you to ask him?

Just read that again, and can see OP meant she doesn't visit the brother at his place which is 2.5hrs away. Even still, 2.5hrs if people love each other really isn't that far. I have friends that live that far away and we just treat is as our weekend away, hotel and everything chucked in.
