Relationship transition?

My boyfriend and I work together. Where we work we are not suppose to date co-workers. Thus, he has decided to leave his current position for another job. He and I have spoken about the future. What we will do. What we can do. However, I would like some helpful coping advice for how to cope with his absence at work. I will miss him around the office, and miss getting the chance to speak with him. Helpful suggestions please.
