It is oh such a fine line and my advice is to lean on the side of caution.
I found myself relying on my gut and only when I was not emotional. You are right to not jump in and you are doing what I consider great by knowing that you may need to take a step towards her.
For me it is touch and feel, slow and easy, and such a fine line it is.
Don't move on emotion, but allow emotion to be there. Keep yourself healthy and take baby steps. Erase any expectations, as they will show and hurt.
Slow and safe, but listen and learn.
