Well I'm not married and I'm not a therapist and I don't know either of you, but here are a few things I'm noticing.
You keep cars/trucks for a long time. Your husband might see your bike the same way as a car -- it still works, it gets you where you want to go, so you don't need a new one. I have some family members who are like this -- they keep things forever, fix them when they break instead of replacing them, don't see the point of getting something new just because it's considered "better technology," because the old thing still works fine.
I think PCs are in a different category from bikes -- if you don't upgrade or replace them, after not too many years they fail to work well for you. You need more RAM, more memory, a new operating system, USB ports instead of disc drives, etc. Otherwise you can't install the new software you want to buy or it takes forever to download anything from the internet or there are security issues because the old operating system is not supported anymore.
But a bike can still be ridden, unless something physically breaks on it. And if you're not the one riding it for hours on end, you might not understand why it's worth a couple of thousand dollars to replace a bike with something lighter or better fitting or with components that work more reliably.
