Well, my current girlfriend is supportive of my hobby, though she isn't interested in taking it up herself. She's been honest and says she thinks there are better ways to spend money. She knows my money is mine and this hobby is preferable to me being in strip joints, buying porn or drinking.
Thankfully she has a higher level of maturity than a previous girlfriend I had who was one of those "Whats yours is ours and what's mine is my own" types who would think nothing of fetching one of my finished peices off the shelf to let the destructive kid of some guest play with.
She collected teddy bears and God help you if you went near them, that would not have bothered me if the teaddy bears she collected were truly collector's bears, you know, Steiff or Gund or some other high level brand. She collected the K-Mart sale day specials, made in China or wherever and treated them like investment grade bears. I got the reaming out of my life the day when a visitor's little girl innocently went into the room where she kept the bears. I ended that relationship right there. She can have the bears and I hope she's happy.
My current girlfriend thought it odd that so much research should be put into a model, but she is a good sport. Back in May she told me about an exhibition of the Czech Armed Forces she was working at (she's a civilian employee of the Czech army). I would not have known about it otherwise and would not have gotten the opportunity to crawl all over and inside some awesome Eastern made military machines like a Mil-24 Hind helicopter and a T-72 tank to name a couple.
I think this ones a keeper! :-)
