Going over the past, it does help heal, at first. After some point, it just keeps the wounds open, the very same ones it supposed to help heal... When you ask a question over and over again, and the answer you have come up with, is always the same, but still doesnt "cover" you because "it is not fair, it shouldnt be this way, how did we end up like this etc etc ", you gain NOTHING going over this because you have thought of everything possible, then..., it's just beating a dead horse. Time to drop it. Put it to rest. At some point you have to know when it is healthy for you to stop...
