I would sign when you're comfortable that the settlement is fair, but wouldn't delay it beyond that point.
Do stay dark though -- it's a huge test of your will. Realize that when you reach out you do so with hope. W detects that hope and translates it to pressure and guilt which she desperately wants to avoid and thus runs farther away from you.
You are "safe" to approach at the point she is *convinced* you want nothing more from her -- that she is neither responsible for your sadness or keeping you from being happy. That's when she will reach out without worry and you have a shot at rebuilding. Before that she might make some tentative overtures and how you respond will set the tone for what follows. Be happy, be busy, don't be too available. Your goal is to fill up your life with non-W stuff, the more the better.
