As in so many things, in a relationship, it all comes down to a matter of trust.
As for mine, she is still afraid of guns but slowly breaking down and willing to come with me on a range trip some day. Ill keep working on her but I digress....
Any limits that I might have are strictly a matter of money. When I come home from a GunShow, she always asks me what I bought. If I buy nothing, she gets slightly disappointed. If I buy something, she always wants to see it and have me explain what it is. If I sell something, she gets a bit upset. Doesn't hurt that every once in awhile, I have the opertunity to slip her a Ben Franklin. She likes to collect them....
If I'm going to share the wealth, it's going to be with my spouse and kids. ..
Be Safe !!!
