Mine asked me this as a hypothetical.
I told her, as harsh as it may have been, but I said, that they were a part of my life, they don't consume it, but my collecting is a hobby of mine and it is part of me.
If she didn't like that, I'd be happy to compromise, but I wouldn't get rid of it completely.
Ended up later compromising by agreeing to spend less, which was kind of being done anyway because I had to pay for the dates and typical boyfriend stuff...
