The people who want to feel like "family" when you're not have to be fed something. Feed her the info that is of no consequence. If you wouldn't be upset to tell her, do so. That way she feels connected and close to you, while you haven't revealed anything that actually makes you vulnerable.
I have a manipulative, back-stabbing colleague who wants/needs to feel like she's mentoring me. I feed her the non-consequential personal tidbits of my life to make her feel good about our relationship. I keep all my work & strategy private so she can't sabotage me.
