I am in much better shape than my current BF. The first few times we rode together I thought it would be fine - I neglected the fact that those were my first few times on my road bike, and I was being ultra-careful with those skinny tires! Now if I go slow enough to ride with him I feel like I'm not getting a workout at all. I know I could just ride on my own instead those days, or stay behind him so I don't leave him in the dust...but I always wonder if he's actually working hard or just toiling around out there, and half the time I want to get in front and push him to go harder. For now, we ride seperately.
