add a friend on facebook

[waiting for someone]

I added a friend on facebook weeks ago, but today I saw"friend requested" became"add as friend" again,does that mean he rejected the friend request?
well,thank you then. at first, he asked me to add him,but actually I've never use facebook before,so I applied an account for him. I just can't understand why he asked then rejected?
at first he told me to search his name,but I couldn't find him,then he told me about the details of his profile, finally ,I found him,but he rejected it? can somebody tell me what it means..
