Vinny, is interesting you bring up your post (unwitting) DB success. When my H and I were saying, we broke up twice. Each time he came back after I went dark.
I'm no expert, as I'm going through the separation process now, but I'd say don't give up. It doesn't really follow that there is nothing left to save. If you recognize done of the things you can do differently and be better at them, you should DB to stabilize things them work on the aspects of the MR after that. IMHO.
