So he is trigger-happy. I was in the same situation on Sunday. Went on a restaurant date with this guy Randy, from OKC. In passing, during dinner, he mentioned that he was telling others in his circle of friends about me. As in "r/s". At first I was a bit uneasy. Sure, it is an honor, but I am not sure I am ready to take it... But then I relaxed - so he sees it the way he sees it, and there is no harm in it.

As Larissa said, treat it as compliment, and, do not feel that you owe anything to him just because he changed his status.

Another rather radical idea... pretend that FB did not exist. After all, most posters on this thread went through dating before the advent of FB, proving that it is possible. If you remove FB from the picture, there is no more problem for you, right? The problem is due entirely to the ubiquity of FB.
