It means she doesn’t want to hug you. And until she trusts you enough to tell you more, that’s all you need to know.
As far as I’m concerned, automatic hugging has always been part stupid, part sleazy. Seinfeld told us to “get off the ‘kiss hello’ program” almost 30 years ago, and I thiink it’s time the obligatory hug followed it into the dustbin of history.
Don’t hand me no lines, and keep your hands to yourself.
