I don't have to bullshit my missus.
She never really complians about my spending, (somewhere around 25k on my 4by in last few years + other toys)
I tell her what I want to buy, then buy it. She always says, "if we/you can afford it then do it"
I have few hobbies/outlets and work my ass off so she knows it's important to me to enjoy what I can when I can.
I never say no to her either, me wanting a new bike means she wants a new bike (already has 2 mtb's she doesn't ever ride) but hey, I'll find some cash somewhere to buy her a new shiny garage ornament and she'll smile and be happy.
Best comment from her was on a 4wd trip after I'd failed miserably getting up a pretty cool track (took one of our guys 15min to get 30metres up it)
She turns and asks what else I wanted to do to my car and how much I think it will cost, I start rattling off the mod list with a fair few of us standing around when something clicked
I asked her why so interested all of a sudden...
"I just want to know when we can get a new bed, but that won't happen till you've got everything for your car"
(3yrs later, still no new bed lol)
Other guys were gobsmacked, but she's just like that. Puts my happiness above hers.
