If you are being blackmailed, no matter how hard it is (because what you are being blackmailed about will then come out), you should take the matter to the police.
If you are being blackmailed, it is important to not give in to the demands of the blackmailer. Document any evidence of the blackmail and report it to the authorities. Seek support from trusted individuals and consider seeking legal advice to protect yourself.
Just stay clear. Do not disturb the relationship.

Yes, not all blackmail is illegal or undesirable. For example, "Go to detention or I will call your parents," is technically a form of blackmail, but hardly illegal. If the blackmail is illegal, the blackmailer should be arrested. This assumes that someone aside from the blackmailer and the person who is being blackmailed knows about the blackmail. If not, it is unlikely that the person who is being blackmailed will tell anyone they are being blackmailed and the principal isn't going to say anything.

Blackmailing means threatening to say something bad about you, unless you do something that the person doing the threateníng wants. Unless you've had that threat you're not being blackmailed.
What the hell mate? You wear the pants. You make the decision not to be "emotionally blackmailed". Can you elaborate on what this term means? All I can say is put your own integrity before any person, including her, and build more mental strength by thinking about what it is you stand for. This is not mean, it is stabilising, which she will be happy with and most likely stop doing whatever she's doing. All the best.

Blackmail is a situation in which you agree not to share some piece of information in exchange for money or cooperation. If you have a crime to report and go straight to the police with it, you will not be blackmailing anybody. If you are being blackmailed into withholding evidence of a crime, you can't prevent it from being blackmail. You either have to cooperate or report the crime and ask the police to protect you.
