Ok, so it's another IL's AIBU! Dh has a very complicated and dysfunctional family. I have struggled over many years to fit in or be accepted by them and mostly failed. We now tolerate each other but I honestly can't say there is any genuine warmth on either side. If it were not for dd I would cut ties altogether and I know dh feels the same (they have been incredibly hurtful to him over the years).
Anyway..into this complicated family (think 6 siblings, 4 different combinations of parents) a much older stepsister re-appears after many (over 20) years absence, she lives in a different country where other members of her branch of the family live. Everyone seems to be glad to have reacquainted with her. She invites herself and her dd over to visit about 4 years ago. That was fine - all dh's siblings gave the impression that they were happy to have her come and stay. In reality it all fell to us. This is typical. Some of them had 'other plans' or just sort of backed out of it when the time came. Dh ended up taking a week off work to ferry the stepsister about the place and show her some of where we live etc. I found it fairly stressful never having met the woman before in my life and her dd is a spoilt madam.
She lives in a major UK city and has never ONCE in the 4 years of reacquaintance invited us over to her for a visit. Every year since then she has invited herself here - free holiday basically! It always involves dh taking time off (he is self employed and the other siblings say things like 'can't get time off work to collect / drop her to airport).
She has just sent me a message inviting herself again in a few weeks and frankly I am fed up of it. I know it will involve having to do a fake 'happy families' situation with the other siblings and I am sick of them all (there is a lot of history)
Anyway - aibu for just not wanting her to come here again? And for feeling annoyed at her for never returning the offer? I Even if we say the timing doesn't suit us this time, perhaps she'd like to stay in one of the other houses she will just postpone the trip and keep suggesting other dates till we agree to one of them.
I am sick of her and her dd, but am aware that it is dh's stepsister and in some ways he is happy to see her. It's just that most of the work falls to me.
