That's why you need to share everything about your Bitcoin specially to your partner. Cause you can never tell what will happen. It better to be prepare than nothing, so that if ever bad happen at least theirs someone who can manage your Bitcoin.
without telling other people that we have bitcoin, no matter how much the amount, that bitcoin cannot be used by anyone and will still bury with the wallet. but for myself, I will tell my family that I have bitcoin and I will give to them and tell the information to them about how to use bitcoin so they can continue what I did and they can have a better life in the future. gladly, some of my family know that I am involved in bitcoin and they support me and they have their own bitcoin so if something happens to me, I guess they will know what they supposed to do.
