Ah keberoxu, that reminds me of when I was going through a very tough time dealing with a workplace bully who was my manager.

I went to a women's group event which was supposed to be a celebration and a chance to socialise with good people and a woman I didn't know sat next to me at the lunch table. She suddenly started giving me an unwanted psychic reading, in front of everyone else at the table. I was so upset already about the months of bullying and then about her invading my psychological space without my permission. I jumped up from the table and went to the bathroom and cried my eyes out. I was so angry that she thought she had the right to launch into this invasion of my private space.

Negotiating with others who are invading our private space is not easy, but it can be done. I went to an assertiveness training session many years ago and it was very helpful. One tip was never to say "sorry" at the beginning of a statement about not wanting to comply with a request because it gives the other person a chance to continue the conversation. If someone asks you to go to lunch tomorrow, for example, and you don't want to go anywhere with them, don't say, "Sorry, I can't make it tomorrow" because they will say, "How about the next day?" and so on. It is a clearer communication to just say, "No thanks. I'm not interested".

Then polite but assertive repetition is a good tactic, e.g. "No thanks. I'm not interested" in response to any attempts the other person makes to repeatedly put pressure on changing your mind. Quiet but firm is the best tactic that I have found.

I also find it helpful to think through my tactics. I often write it down and then clarify my thoughts and reduce them to one or two statements which I can repeat as often as necessary until the other person gets the message.

I suspect you are the latest target in a long line - newcomer to the home and someone she sees as a possible new person to bother because all the others have sent her and her behaviour away.

Keep calm and work out your tactics.
