“Its quite common for long term roommates (housemates, whatever) to end uphaving joint accounts, shared assets, often buying a house or car together. When the relationship ends (voluntarily or through death), it can create great complications (and of course, great opportunties for parnassah for lawyers).
And it has nothing to do with gender or sex.”
Where do you live? I have never met or heard of a single person using the arrangement described above. Neither has my husband.
It makes sense to share grocery bills, cleaning expenses, etc. But a joint bank account and a shared car? Why would anyone do that, and where are they hiding?
