My thoughts are this is Pip singing to another girl, probably much younger, who is trying to move in on her territory (probably involving a man) and using poor manipulation tricks to try and discredit Pip. Pip warning her that she's on to her and she can't pull the wool over her eyes. "You gotta right to know" is her telling her out of courtesy and some respect that her attempts are useless because Pip knows every trick in the book because she too was once this girl. She also hints to a certain respect for the 'other' girl by saying "Now I don't mind a dirty girl". I think that Pip is saying - I know what you're up to and you're not gonna get away with it but it doesn't mean I don't respect your position because I understand, I was there once just like you. Just don't f*ck with me. "I'm at your door"
