I wouldn't say to her that she can rely on you. That can come off wrong. What I mean is you aren't going against her or being a detriment. Does that make sense?
If you're negative or needy around her, that is a detriment. Be cheerful and pleasant. You don't have to get her coffee or anything like that but just be good.
Hope that helps...
