Query: Thinking about you, just not talking to you

Highly intelligent friends and lovers meet at 6 year intervals that coincide with the waxing and waning of a comet that one of them has discovered. I enjoyed the authors method of tying astronomical and human behavior and his philosophical insights of both. What bothered me is the characters behave too much like the orbiting bodies they study, circling each other but not communicating. I know that is the point of it but it was just to much to be believed. This thoughtful, intelligent novel of life, love and astronomy is worth the read.
