Hey rop, I think that you need to not worry about telling her ANYTHING. She will think what she wants and nothing you say will change what is in her mind already. I think that it is great that she is ASKING you what is up...this is showing a sign of concern....but I think it is to justify what SHE is doing.
ping1: take everything that is going on, what is being said and write them down. This is exactly the feedback you need to correct your past mistakes. Now, whether or not things work out, at least you will have this as "I didn't know I was doing that" kinda info.
