Does your spouse have their own bike?

My other half has her own bike. I am somewhat selfish and my bike is one of the few things that I was willing to share once she started riding more often. Am I alone or there more of you out there that feel the same way?
I won't share my bike, and he wouldn't either, that's why we both have our own. I think it's great when you can share you bike. I guess we are kind of territorial.
I am not married but I refuse to share my bike with anyone. So I guess when I get married I will have no choice but to buy another bike, that is if they like to ride.
