Get her out there and get her involved. My wife wasn't a deer hunter, but was comfortable with guns and would shoot varmints out of her garden. A few years ago I got her interested in my x-bow. She started going with me. After I've shot one, I sit with her in the ground blind for the rest of the season and we have a great time.

Re: the money, we review finances at the end of every month. Whatever surplus (after bills are paid) there is gets split 3 ways: me, her, our savings. She does what she wants with her money, no questions asked. I do what I want with mine. We have my guns and bow, her guns and bow, and 'our' guns and bow. I'll bring a shootin' iron home from a gun show and ask her 'do you want in on it?' If so, she foots half the bill. If not, it's mine.
