Urgent Facebook problem!!!?

[Pink Girl]

While looking up coworkers on facebook, I accidentally sent a friend request to my boss (who I have a crush on), and immediately canceled the request...but I was wondering if he will still be notified on Facebook, his phone, or receive an email...basically I want to know if there is any way he can still find out even though I cancelled the request 5 seconds after I sent it...I am so worried things may get awkward if he finds out about the friend request...thanks for your help...
