Bright, There's nothing wrong w/you sending him his mail since he's on the move quite often for his job. However, if he's becoming more and more distant, it could be that he's going into a deeper withdrawal due to depression or he could be becoming a distancer to see if you will up your communication w/him. Keep in mind that there could be any number of reasons why he appears to be more distant. It could be work, new friends, depression, new interests or just plain tired and doesn't know how to mend the broken fences w/you.
I wouldn't worry too much about either of you being "exceptions" to the dance of pursuit/distance. I haven't seen much of the "dance" between the two of you from your postings because you both have a business that keeps you in touch w/each other periodically, as well as good friends who stay in touch w/both of you. Is it possible that your friends are keeping him in the loop as to what you are doing w/your life? The reason that I'm asking is that your friends share what's going on w/him w/you and they could do the same w/him about you.
Bright, when he's ready, he'll contact you. They always do and when he does, just be yourself.
