My friend is in the midst of a custody battle with her ex. I am on good terms with both of them. I've known her longer and seen her more often, but I like him well enough and have nothing against him. I see both of them often now, because our children are friends.
She keeps trying to get information from me about all the details of his life, and makes no secret of the fact that she plans to use this information against him in court. None of what she is asking is particularly sensitive information; I just don't like the idea of passing it on. She wants to know, for example, "When did you see him last? Where did you go with him? Was his new partner there? What was he saying about me?"
She seems to have assumed that I am "on her side" against him. Actually I am not. As far as I can see, they both appear to be good parents. Even if her accusations against him are true, they don't seem particularly damning in terms of his ability to be a good dad. I've never told her this because I don't think it's my place, and anyway she has never asked my opinion.
So far I have dodged her questions by being vague and changing the subject, but she is very persistent and it's getting hard. How can I deflect her questions?
