I can't speak for anyone else here, but any kind of emotional attachment/interaction that would occur with my W would just confuse and hurt me right now. At least W knows that and has made sure not to pursue it.
But I would caution you. "Pursue" is pursuit. If you're okay possibly getting hurt again, and I think it might sound like you would attach meaning to the physical side of things but that's just my interpretation, it could leave you in a worse state if or when she pulls away again. That's the pursuit-distancer dynamic.
Plus if she's still in the uncertain zone, a lot would be riding on it (pun intended - sorry) and it could mean nothing to her, while meaning everything to you.
I'm a relationship guy, I figuredthat out a long time ago, so it has to mean something to me. Others here aren't and I understand and respect that. Everyone is different.
Whatever you do - make sure it is only for you, and not for the R.
