So sorry to hear about your loss and DH's illness. One idea that DH might like, and with all that's going on with him, might make it easier for you to take the time for this -- if he can travel, how about he meets you for the overnights - if it's just 40-50 miles, he can drive to the campsite and you can spend the time together. You get your riding in, and he won't worry as much.
