Its not really healthy to obsess over anything. You can love your sport, but if it is interfering with a personal relationship, I just don't see the value. I love cycling as much, if not moreso than anyone on this board, but I have outside interests. For example, I love automobile racing, I like animals, I like hiking, jet-skiing, snow skiing, in-line skating, and I really enjoy swimming and being a beach-bum in the summer. Cycling is my main mode of exercise, and it is my favorite sport, but it is by no means an obsession. If this man is so obsessed with cycling that everything he talks about is cycling related, then that is not healthy. Try to talk to him about persuing outside interests, and maybe if all else fails, throw out an altimatum. If he doesn't care enough about you to change, then you may need to reconsider your relationship. Just my personal belief.
