I'm amazed running into this thread. My wife has not asked for a spreadsheet, but I decided to make one just to keep tabs on my inventory/LBA.
In any case, she is always astonished at the price of glass, but pretty much allows me to do "my thing" because:
1) We have separate finances and bank accounts...
2) But, we have full disclosure of said accounts.
3) We have a communal account for bills and the household budget.
So I get to spend my reserves the way I want and she with hers. Despite that, I know there are underlying concerns about the money spent on glass, so I try to put her mind at ease by taking awesome pictures that she can put on her Facebook page
