Re: Your wife
Like all marriages, there is the US/WE and the You/Her. Both are really important. You have to be what you want and so does she. Sometimes when people evaluate that it means not staying married. But, you also have to look at how you change. When you're twenty some things matter more than others. When you're forty stuff that used to be important doesn't matter anymore. In fact you look back at a lot of things and realize what a waste of time and money it was. But spending time together and appreciating what you did when you are younger is every bit as important. Shows, taking kids/grandkids, spending time alone at a nice place. That's important.
I enjoy having guns. But, like any other hobby, I get to do it, but don't want to obsess over it. Games, cars, antiques, guns, are all cool stuff. But if you don't, at some point, put your relationship first, it will fail. I've seen too many relationships get destroyed over money and stuff. Especially when what they needed was each other.
Buy the guns you want, if you can afford it. Make sure you have enough set by to take care of your family in case of emergency. Guns may be necessary for that. But a whole collection won't help. Other than to bring in money if no one buying knows how bad you may need to sell them.
