What do you mean by timeframe? As in the time between DB and separation? Or the time since then? Honestly, there is no standard for any of it. It is what it is and it may be different for each case. One thing that is for sure is that nothing will happen quickly. This is a freight train full of inertia that isn't going to be "snapped". She isn't going to just "wake up". So, you have the time now. Use it!
