Hmmm, i don't think you can give a black n white answer to this, we wont pissibly know until it occurs. Without coming across as heartless, I have to say life goes on, just taking a day at a time is all anyone can do.
I know 1 thing I have taken on board, that is to make sure I have all the i's dotted and t's crossed regarding bills/outgoings. I learned that from my neighbour whose husband did literally every mortal thing regarding bills, insurance, car, blah, blah and when he died suddenly, she told me she was at her wits end with it all, had no idea where to start, had to get a friend of hers in on the whole problem ( lucky he had been a bank manager ) and THAT was while she was in utter grief and loss, a terrible time for her, so THAT is my practical problem sorted, I wont be able to do a thing about the loss of my husband and to be honest I dare not give it space in my mind, too upsetting.
