Sister is very ill, terminally, has teen kids and is looking at additional private health care.
We've had some heavy hints dropped about how much this will cost.
Her family also have private school fees, and over the last three years spent considerable sums (over 100k) on a hobby plus various bucket list exotic trips. We don't know what their future plans are for funding the ongoing costs of teen hobbies and fees.
We earn less, spend less and don't have a terrible diagnosis hanging over our head.
I feel sad about any family going through this.
But AIBU to not want to contribute financially?
My judgement is clouded because before all this she was quite horrible to me and that hasn't changed recently either.
