A Creep Keeps Adding me on FaceBook?

[Melondy]

So like last year I added this dude hes like indian and I added him because he was friends with my friends.. But how can he know them when he lives in India? I look on his friends list and they were all like little girls as his friend.. I was creeped out... I asked who are you and he was like saying hes a dude and crap.. He put on his status hes looking for a cute young gf but he looks like hes 20 yrs old.. Al the girls on his friends list is 10-15 and im scared.. So I unfriended him and he said why did you unfriend me? I didn't reply back.. So anyways a year to now I went on my facebook to check messages and he added me but guess what? With a different account! Then he said hi how are you? I said Hi i'm good who are you? He never replied back.... Should I block him and unfriend him.. Because idk him and he looks like creep I mean he doesn't but he sounds like one.. He looks like a normal man! So help
he finally replied back and said im ariel...and u r very very very cute
and beautyfull and I said ok thanks.. And then he asked how old I am..
