She's looking for attention and needs to feel wanted again. It's not going to help in the long run but its what she wants right now because it's what she thinks will make her feel better; I know, because I did the same thing. If you try and outright stop her or discourage her it could sour the friendship so I would just be there for her as much as you can. In the first 4 months of my separation/divorce I had more bad dates and bad sex than the previous 30 years of life combined. She'll eventually crash or burn out and get things into perspective and decide its time to start healing properly. It's kind of like getting an addict into rehab; you can't force them into it, they need to bottom out and want to go. Best you can do for now is offer to hang out and be a much of a distraction as possible.
