My Mind Tells Me That Something is Wrong.

Good evening Aunt Amara. Please, something has been bothering me since. A guy sent me friend request on Facebook which I accepted. I don't know him in person and I hardly chat with him online. He claimed that he's based in Germany. So, I then asked for his Skype identity and mobile number which he gave to me.  I only called him twice on the number he sent to me. 
So, at a time, he said is like I'm a busy person that I hardly chat with him online. I said yes.
