Agree with Ken. Don't get into the mindset that things like hugs or ILYs aren't permissible. Everything that works is permissible. The hug was a totally appropriate approach to a woman that was emotional. So is showing empathy. Try to keep in mind that you are validating and empathizing, so don't go all Mr. Fix-it on her.
Personally, I did get a kick out of her being mad at YOUR family that they aren't calling and showing concern. So, they are also supposed to be mind-readers?
