I used to think that it would be the ultimate to find a woman who liked my hobbies as much as I do since I had a lot of experience finding women who actively didn't like them. I now realize that I found the perfect mate because we're VERY compatible on kids, family, religious outlook, politics, etc., and she is completely apathetic about my pasttimes (as I am hers) - she is more than happy that I enjoy sitting around watching basketball and listening to music endlessly. She's just glad I don't make her do it with me. I guess if I could have everything else the same AND have her be passionate about music and gear, I'd love that too, but not at the expense of giving up something else. And I couldn't go back to having a significant other who resented my pasttimes.
I certainly wouldn't get out of the relationship based on this experience (actually, I wasn't sure that was a serious question), but I'd certainly try to understand what it's telling you if this has the potential to be long term. If she's telling you she resents the hobby, the money, etc., and those things are important to you, you need to decide how significant they are to you. -Kirk
