Funeral up coming holiday

No easy answer to this one, its all very personal and I'm sorry you have this worry about your sister in law, its a sad time for you all. At the moment your sister in law is still with you, she may live past your holiday, its an unknown. For myself, as M0nica says most families consider a funeral date around the availability of other family members. You plan to be away for just one week so it seems very unlikely to be a major problem.

Having said that it is about how you feel. Its no good going away and then worrying that you shouldn't be there. So full circle, its very personal and leaves me with questions rather than answers. What does your husband think? How much support do you give your brother in law at the moment? Something to decide between you, it feels important you both agree.

My opinion is that funerals are for the living so if you are close to your BIL then you have to be there to support him.Simple .

If you are that close surely your (DH's) brother will arrange the funeral for a date when you are available.

When fixing a date for a funeral, as well as practical matters, like space availability at the crematorium, which normally puts a funeral back anyway, most families take into account those in their close family who would want to be present and their availability. Well, we did.

It all depends how close you as it’s your husbands family member it up to what he feels you should do Best thing for him to talk to his brother and explain he’s worried and don’t know what to do and be guided by him
You could cancel and she lasts another three months See what her husband wants you to do and follow that it’s only a weeks holiday after all and you don’t say if it’s overseas or within driving distance to return if necessary

DH's niece died when we were on holiday, we rang and spoke to BIL and he said we should stay on holiday. We were in the south of France in our own car and would have had to drive back.
If there is other family for support, it may not be as important for you to be there.

I understand your feelings especially if you have had to cancel your last break. You could always go on holiday and be prepared to fly back if necessary but would it spoil your break? If not I think that’s what I might do but this all depends on your relationship if it’s close or not.
Tough call.

I’d cancel for sure if my sister’s husband had died. In fact I did.

No way would I have gone away and left her to cope with his death and the funeral.

And the days after.

In your position I’d wait until after the funeral and then take him away for a break as well.

But that’s just an opinion.

I would cancel any arrangements for the foreseeable future.

I returned from Australia for my fathers funeral after he died quite unexpectedly a few days into our holiday.
I would have returned anyway to support my mum, although I have sisters they had to return to work after the funeral.
It is possible to organise the date of the funeral, in fact unlike ours, it probably won’t be for a few weeks after the death.
Would this be possible?

Turn the question around, if your DH died would you expect his sister and family to be there?

Well, I would.
