To feel a bit hurt

[NYWoes]

Close family member asked me to make plans with them for NY Eve and day because their partner was working so they weren't alone.
I made plans and said to let me know if anything changed.
Last week they said they did not fancy going out after all and could we do it at home instead. I was happy to.
I paid for nice food and drinks etc for tonight and we had plans tomorrow too.
When I mentioned what they wanted for a nice meal tomorrow they said they were happy to have what was in.
I thought that was strange as usually we have a meal but whatever.

Turns out my suspicion was correct and basically they are staying for an hour to eat tonight then leaving to spend the weekend with someone else.

I usually do something else NYE and changed to spend this time with them and now I am going to be the one alone.

Aibu to feel a bit hurt and in general a bit pissed off?

Did you not say this to them when they said they were going to leave after eating? I'd have pointed out that I had changed my plans at their request as they had nobody to spend the night with.

Of course YANBU. That is shitty behaviour from your 'friend'/user.

I'd say it to them and never again see them as a genuine friend or a decent person.

I’d really recommend just telling them in a non confrontational way that you felt hurt. Honestly I used to say quiet and it just builds resentment.

I actually reached my limit of disrespect with an ex friend and dropped her. I feel so much better for it. She has since tried twice to get in contact but it’s far too late. If you’re a good friend they will feel your absence.

Yes.
They told me that they did not understand why I was making a big deal of it basically.
They originally offered to stay until just after midnight tonight and did not understand why i said that sitting with someone who clearly wanted to be elsewhere was shit.

Appalling behaviour. Tell them so and don't put yourself out for them again.
Wishing you a fab 2026, OP.

It's rude of them.

Lesson learned OP, don't change your plans for them again!

Lesson learnt. Keep your boundaries crystal clear in future. They’ve been selfish but your boundaries are your responsibility.

Thats very rude - leave that 'friendship' in 2025 - thank you, next!

Yeah that’s shitty behaviour. Yanbu to feel hurt.

It's a family member (sister?), not a friend.

If it's a pattern of behaviour s/he is a bit of a user.

Very rude

I'd be annoyed rather than hurt. You changed your plans for them and they dumped you for a better offer. Who does that?

Well at least you'll know for next time and tell them to sod off

I wouldn’t do anyting for them ever again.
