. It's the other way round in our house. I have to eat all chocolate the minute it gets through the door where dp can leave his in the fridge for weeks (or that's what he thinks, I don't tell him that everyday I eat it and replace it.......)
I bought a great chocolate bar a few weeks ago. 50% his and 50% hers. Except that in reality it was about 25% his and 75% hers. sainsbury does them as part of a novelty range which also includes bars of 'emergency chocolate'.
maybe you should get some of that for the stash he knows about. Then hide the real stash elsewhere!
i have a secret choc stash,and have learned to eat it with stealth once my daughter who was a toddler and was playing with her brother and their toy had fallen right where the stash is hidden,my son thought it was strange his sister had took ages getting out of the corner in the living room (the stash zone!) he went to investigate to find his toddler sis curled in a ball eating huge mouthfuls of choc from the giant cadbury bar i'd hidden, you see its genetic she just knew how to eat the choccy with stealth and the non sharing approach was already in her
