Newtobikes---I also used to feel guilty for riding, as it took time away from my family. I finally figured out that if I rode in the morning when they are still asleep, no one will notice, and I have nothing to feel guilty about. (I have since realized that the guilt was self-induced, and now I'll ride anytime that I'm not "needed" at home.) Can you ride at a time when you aren't "needed" by your hubby? Early morning or some other time that is already not a shared time? Try to put into words the joy you get from your rides. Once your husband realizes how much you enjoy the bike time, hopefully he will encourage you instead of guilt-tripping you.
