Tell your husband to run on his own. This is why running sucks as a group exercise.
Try working your aerobic system. That means you should be going slowly enough that you just barely feel out of breath, or even that you have no problem breathing. That might be a fast walk for you at this point. If you feel like you can't breathe enough air, your body has shifted into anaerobic mode, which is going to wear you down a lot faster.
Or get some rollerblades or a bike and go with your husband.
