My wife knew what she was getting before we got married (40 years ago). She supports me in buying whatever rifle or outdoor item I need or want. Likewise I support her. We're not rich and both of us are low maintenance. She likes to decorate our place and I like to build rifles, reload, shoot and hunt. We are not big travelers. We don't go out a lot. I reload, build rifles, hunt three months or more, and shoot. She does her thing.
We both support each other and no real questions are asked. In fact, she has been cussing me for not buying more reloading components when Biden was elected. She keeps saying "I told you when he got elected you should buy up a ton of stuff." Anyway, she is 100% supportive. And yes, I have too many rifles. But we both think they are a good investment, too. When you live in rural Wyoming with your own rifle range and gun shop, your perspective might be different than most folks. But our deal sure works for us.
I married the right girl for me and am thankful. No secrets needed.
