As actions speak louder than words, could it be possible that the hug W gave you was a thank you?
Yes, you did the right thing. Leave it at that with zero expectations of anything.
If you think about it too much it will end up confusing you because you'll play out every possible thing that any of her actions might mean. I'm willing to bet your W's fog is so thick that she has no idea what anything means. If you believe she is a MLCer, I can tell you that they are totally emotionally driven. Not a lot of room in there for rational thoughts.
So yes, get back to focusing on the only thing you can control, you!
