I will have to say my wife is extremely supportive of me and my hobby. She quite often travels out of the country and always asks me to provide her with a list of shops and directions on how to get to them from her hotel. She has brought back some beautiful figures that are no longer available and she has found in remote Hobby Shops around the world.
She also came home one day from doing some local shopping and handed me a carefully wrapped bag of paint brushes. She had been into Michaels and they were running a 40% off all brushes. She bought 160 dollars worth of brushes for around 90 dollars. They were all sizes I used, so she knew what to buy.
She has asked me to keep a desktop listing (she would have easy access to) of the figures I would like to have.(Christmas & Birthdays)
My wife is also my best critic (sometimes brutally) and likes to look at each figure I complete. As I have alot of figures arriving throughout the month she has never questioned me or complained about so many figures or how much they cost. Being retired now and also painting figures, I quite often take some (notice "SOME") of the money received from painting for collectors and use it toward projects around the house.
Remembering back to what it was like with my ex-wife, and total non-support of the hobby, I would have to say the support is well appreciated.
My wife has also helped others over the internet set up mail accounts, how to use google, etc and is the "House Guru" when it comes to computers.
