Be honest, he'll get over it soon. 
I know that with me, I bought a lot of gear, even though I didn't have the money for it then. In the end I found a good set-up, and I don't buy that much (I hope).
Still it's also a hobby for me, that I share with my boyfriend even though he gets a bit upset with me buying expensive tanks, he gets over it real fast. I was a heavy smoker and with the Norwegian taxes on tobacco, I still save a lot of money. I've spent 1260$ on gear and juice since I started vaping in October, and since I completely quit smoking in January I've saved over 2000$, so it's a win! And I have a lot of gadgets to show for it, instead of a full ashtray.
