No, she doesn't. She said we would talk about limits if she felt email and phone calls were causing a problem (there was some other slightly more delicate phrasing), but she has never mentioned charging for them. She seems to want me to reach out to her when I need to, and I think she knows that charging me would make me feel like even more of a burden to her than I already do.(i.e., I would interpret a charge as her saying "Don't call or email me.")
