Pick a couple of items that she will likely want, not because she will want them but because you use them, and make them non-negotiable. Mugs and decorations, who cares? Appliances (I am assuming small appliances?) Pick a couple you will absolutely not part with and then let her choose from the rest. Pick your battles wisely. Mugs and decorations are easily replaced. Small appliances likely are as well, and how often do we seriously use small appliances. In my case there is a water boiler (cup and mug size, heats water at a fast rate), coffee maker and a very nice blender which would be my non-negotiables. Every thing else she could have.

Try to detach your emotions. Lots of LBSs assign meaning to things when it is really about feelings towards the WAS. "I don't want to let her go so it don't want to let that waffle iron that I only use once in a blue moon go." Avoid that trap. Use logic and reason over emotion and feeling.

You've got this!
