Sorry, this will be a long one.
My dad is terminally ill and will shortly be moving into a hospice. My mum's birthday is coming up. I live about 300 miles away; my sister lives in the same town as our parents, both quite run down areas (relevant).
Since my dad had to move into the spare room and their house filled up with the paraphernalia of his illness, I haven't been able to stay there. I've always visited for a week at the time of my mum's birthday - it means a lot to my mum, especially now she has to cope with my dad, - but for the last few years I have stayed with my sister and her husband.
She and her husband have a dog with complex health needs, which can't be kennelled, so to allow them to go on holiday, I've dog-sat for them several times, travelling to her house at my own expense and taking care of the dog's routine and meds etc.
My usual summer visit was planned months ago, and I booked advance train tickets which were not very cheap, nearly £200.
My sister messaged me today very briefly, to tell me that I could no longer stay with them - her husband's sister is having a family crisis and will be staying in their spare room..
I'm not sure what kind of response she expected, but I messaged back to say it wasn't good news, I couldn't change or cancel my train tickets or my annual leave from work, and I wanted to spend time with our dad while I still could, what options did she suggest?
I got back what I can only describe as a four-screen long text rant, telling me to grow the fuck up and stay in a fucking hotel, how dare I try to guilt trip her etc.
I was shocked. She has herself in the past advised me against staying in hotels in the area as anything remotely in my budget is used by the council to house people, often with issues, drug users and so on. The unexpected vitriol of her reply really struck a nerve and I became quite tearful.
Not to drag this out longer than needed, I replied asking why her SIL couldn't stay in a hotel for the few days I'd be there if this was such a great idea, but I would look at other options, we exchanged a few more messages and some kind of civility was restored, but the tone of her original message has really upset me and I am struggling to move past it.
I'm supposed to be dog-sitting for her in September while they go to Italy and I now feel like telling her to get her SIL to do it (she's barely mentioned her SIL to me before so I highly doubt she would do this). I bought her an expensive kitchen item to cheer her up when she was feeling low, something she really wanted but not something I'd use - she knows I've bought it for her and was thrilled when I told her - I now feel like a mug at the thought of giving it to her.
This has really soured our relationship at a time when it really needs to be strong to get through the coming months of my dad's decline.
How can I move past this?
Thank you to anyone who has taken the time to read my lengthy post.
