We Americans do consume to much stuff but that is a completely topic because this is BIKES we are talking about.

I'm curious as to how often OP and spouse buy new vehicles. Maybe that can be brought into the discussion especially if it is every few years. My DH didn't understand the whole bike lust thing until he finally tried out a bike that was sized appropriately for him. Now, I think if our finances permitted it, he would be looking for another one (and we just got the new ones in March).

Good luck and I hope you overcome these difficulties with DH. Does he have any hobbies that he has more than one thing for?
