I have another activity that takes me out of the house a lot -- playing music. A similar topic comes up on web forums for musicians. One common piece of advice is: "Your spouse needs to get her own hobby." This can be easier for some than for others.
It doesn't have to be the same hobby, and maybe it shouldn't be. For instance, suppose your spouse gets into cycling but doesn't want to ride fast on roads. That's pretty unnerving to most people. Then you'll never be able to train at a level that you prefer.
My spouse got into running. She now runs multiple marathons per year. Sometimes these events overlap, for instance, I can ride my bike to one of her events and meet her at the finish line. One thing you can do is, when you're not out on the bike, take care of **** that needs to get done, so your spouse actually has time for a hobby, and let your schedule be flexible around her interests.
