I'm writing about this as I would like to get different views to know if I am maybe viewing this blindly
My husband and I have separate bank accounts and each take care of our own expenses. He pays for all household related costs, I pay for all child related costs. It's always been this way from when we were dating.
My husband was previously married and his ex milked him in the settlement so he's a bit burnt. A few years ago I was pregnant we had some major disagreements to the point that it was make or break for us. At some point during this stage he moved money around. After our daughter was born, I set about preparing a will and was surprised to find that his savings were suddenly less than half (I knew how much his savings were as we were just the year before planning to buy a property together and spoke about deposits). He pretended to not understand what I meant and hasn't given me a conclusive answer except that he bought shares and reinvested the money.
