Friends with someone on FB that I declined the request?

[Megan]

So Im 13 years old, I logged onto Facebook and I saw I had a friend request, its from this guy named Jason Hanes and I didnt know him, so I didn't accept, I went on his page to block him, it says he gos to High School but he looked like he was in college, he's from Texas, so he's far away from me, but I was just scrolling through my friends and saw him there, I had already blocked him, I went on his page but all i saw was add friend, then It quickly said network error. Am I friends with him or is it a glitch, I don't want to be friends with him, but if I am and try to defriend him it says network error, but it did say add friend but his profile. Am I his fb friend? I don't want him going through my stuff and trying to friend my sister, brother or friends. How do I know if he's my friend, if he's on my friends lists, but then it says add friend? HELP!
