Outstanding, congratulations. I am curious, who was the band, which was the song please?
Now, just have to learn how to hide the expenses of my hobby....
I share this in the spirit of being helpful. You might already have this system, but my friend is married and has the same issue. We hide minis in plain sight with her.
A few of us close 30k/40k friends play at his place. So we leave stuff there, intentionally or accidentally, like we are contributing terrain or forget to pack up a mini.
When he really wants to buy and split something that he can't tell his wife about, such as a big ticket item like Adeptus Titanicus, we split it 50/50, pay for it normally. But then he heads home first empty-handed. Then I bring the stuff over to his place and pretend I made an impulse purchase. I take my half of the stuff, and ask if I may leave his half at his place so I don't have to transport them back and forth...but it's really his stuff, it's just an elaborate hoax that fits into our normal modus operandi. Basically, I'm laundering miniatures for him, keeping it "off the books" in front of his wife.
The trick is not to be too loud about this in front of the wife, like trying to catch her attention to do this. We just get naturally excited because new toys; a wife can sense her husband getting excited about anything that's not her like a 6th sense. She'll come over and inquire, and at that point we barely have to act, we're talking about the game (I was legitimately so engrossed by the leather-bound Titanicus rulebook at that point it was no longer an act); when she feels like she has to ask, and we're not just performing a lie in front of her, it makes it believable. Then we talk about the terrain and, as my friend is also a really good airbrush painter, he just asks if I want him to speed paint the terrain and leave it at his place, as per normal. I say "yes, that'd be really cool of you," and he takes the terrain AND his half of the Titan miniatures among them into his man cave in 1 carry. If anything happens, I take responsibility like I got my friend into this game (even though it was his idea), thus drawing wife aggro away from him.
TL;DR - I don't know what you call a Wingman after you're engaged, but it turns out they're still really useful even after the fact.
