My sister lives in Australia, she lives there with her partner and their two children and has done for over 10 years. Last year, she was diagnosed with cancer and had a horrendous year with serious operations, one round of radiotherapy, two of chemo and a full hysterectomy. She was unbelievably brave and it was a really tough time, my parents took turns flying out there for long periods of time and the year took its toll on everyone. In February this year they all came back to the UK for an undetermined amount of time to rest. Her partner has since got a job here and the rough plan is now to stay until the new year. She is still finding life very tough, coping with two young children and the emotional fall out of cancer and the hysterectomy. She suffers with huge outbursts and since February has had fairly large arguments with my parents, her partners parents...99% of the time caused and instigated by her. That's the backstory.
In January this year, me and DH booked a holiday with my mum and stepdad. A week in Spain in a caravan, nothing fancy, two separate caravans. We paid for ours, mum paid for hers. After my sister got here my Mum started panicking and saying "maybe Stepdad could not come and Sister and her family share the caravan with me?" Mum mentioned it to sister, who was completely non committal and just said "yeah, maybe, if we're still here." I also discussed with sister and she just said "how much do you think flights would be?"
Stepdad has since decided he definitely is coming (serious birdwatcher, wants to see birds in the area
) so I phoned sister and said "this holiday, Stepdad is definitely coming, so if you did want to come you'd need to book your own caravan, shall I look into it?"
She has, completely lost the plot about this. Accused us of "colluding" against her, taking a free holiday away from her, and basically, rather epically lost her shit. She can still come, no one mentioned paying for her, and if it were a case of needing a free holiday, they're just about to buy her a significantly priced ring.
What are people's thoughts? Think I've given all the points.
Hit me with your worst.
