Does facebook let someone know who viewed their page??????? Please answer?

[Sara]

So I looked at this guy facebook page a few times and when I looked him up again I couldn't find him and my friend logged into her account and looked him up too and couldn't find him either then a couple hours later we searched again and there he was and later on tonight we looked him up once more and neither of us could see his profile again. Why does that keeping happening? Does that he mean he blocked me or something or did he delete his facebook both times. And no guys we aren't friends on Facebook which is why I asked if he could tell that I viewed his facebook. Thanks for answering
