You are not notified by Facebook when someone unfriend you. No app has been created yet which gives you the unfriend stat.
If someone blocks or unfriends it works both ways. If someone blocks you they should no longer appear on your fb 'home'
no
You guess
Ask them.
maybe you said something bad about her to one of your friends and unfortunetly they didn't keep it a secret and she found out and so she unfriends you. or maybe you were talking to her a lot on facebook and she didn't want you to talk to her (annoying her)? hope this helps :)

They are surely stalking you on facebook.
When someone has blocked you from their Facebook, you won't be able to know if they have also deleted you.
I guess that you will be able to tell by how they speak to you!
You cant unless you are in facebook
