Support her hobbies, as long as that's not compulsive shopping, and she should support yours. My wife quilts, makes hook rugs and stained glass. each requires specialized equipment and raw materials/supplies. I truly enjoy what she produces and I take an interest in the design and execution parts of her hobby, as well as attending shows and such.
I've invited her to rave meetings, but she has yet to attend, although she does chat with fellow audiophiles when they come over to my place.
All in all, I support her hobbies and she supports mine, and neither one of us takes too much advantage of the other in terms of cost or time.
