I sent my girlfriend a fake facebook friend request?

[LookMomNoHands]

Me and my girl are in a long distant relationship going on 8 months.. i just made a Facebook and wanted to request her but she played around and wouldn't let me add her.

i didn't think anything of it but when it came up again she refused.. she won't even let me be her FRIEND on Facebook so i did something dumb and made a fake account 2 days ago and sent her a f/r..

we were texting all day today and outta nowhere she messaged me saying.. "you're something else you know that?, im not gonna tell you what it is imma let you think about it."

I dont know how he hell she knows but i think she does, what should i do ?
because i was suspicious.
