How did my friend find I have other facebook?

[Lee]

I haven't talked to my friend for few months. I was mad at him cuz he was gossiping about me. I deleted him on my fb friends list. Few days ago, I made new facebook account. I have 2 facebook accounts cuz he wants to add my whole family. NOT HIS. It's mine. HOW DID MY FRIEND KNOW I HAVE 2 FBS. But my 2 fbs do not have the same name. I used the fake names. He try to add me on my new fb cuz I knew he wants to add my family. I don't want to talk him anymore. He's stalker or something.
SO PISSING OFF AT HIM RIGHT NOW!
People you may know? I used the fake names. I don't understand how he finds me.
