I don't know that you can be in a position to be "in charge" of how your friend takes things. She may feel smothered when you give her what you consider lots of room, she may feel abandoned even though you've called her everyday. You have to do what's right and good for YOU, not another person. One can't ever read another person's mind, know what they want and how they're going to react; have to ask them, they're the only authority on themselves.

I think your plan of giving her a few days to settle in again before calling her is a good one. Or, call her and ask her when would be a good time for you to call again, what she would like from you and just gently welcome her home and tell her how glad you are she's back?
