As far as "no ties to Chris" ... there are emotional ones, obviously. But sometimes it is just not possible to be with the people we love. In this particular case, she would have to risk her life in order to do so IMO.
I think it is possible to rehabilitate someone with these behavioral issues, but it takes time and a whole lot of work on his part, and PR people aren't actually part of the process.
The statement People quoted is clearly from Chris' people in my mind, based on the "saddened," which seems to be their favorite word.
Perhaps they are "together," as in physically in the same location. Perhaps what she has agreed to so far is a meeting, discussion, etc. Still far too close for my comfort ...
And I have to think her friends in the industry will absolutely be up in arms & that she will be on the receiving end of some unsolicited advice.
I reckon Chris' people believe it's a very good thing for him if they are back together.
