None of the above: she doesn't ask how I am feeling (beyond indirectly, such as "how was the flight?", when I come back from a business trip), plus there is no physical contact between us, so no hugs or back rubs.
I try to be friendly, such as asking how this school year will be, whether she will be home for lunch, and we can have a simple conversation. More intimate stuff doesn't exist right now.
I am glad for a friendly word, and maybe someday there will be more.
