If you stop riding, you will immediately realize that isn't an option.

Any change is funny among friends, partners, spouses. It isn't just about the bike. And, it isn't just about the gender. She may just be sharing concerns and these are often in the form of her fears. Once she sees how happy, healthy, and energetic you are, it will be a moot point. She will forget she even mentioned it.

Find a riding group quickly. They can give you the social support you need. Many of them have get-togethers for the spouses also . . . and if you can take the kids with you or schedule some kind of 'spa time' for her (or something not sure what) . . . eventually she might find she has time to pursue some kind of interest of her own.
