Yes, the letting go is the terrifying part. It was on a trip to NYC with old high school friends that my wife realized that she wanted to separate. I've done all the wrong things and all the right things since then and honestly I'm just trying to let go right now.
I think that one thing that is very tricky with WAW's is the need to be loving without pressuring. So many of us LBS's were guilty of neglecting our spouses needs and it seems pretty ironic that by trying so hard to meet them now, we may be pushing them further away.
Something that I still struggle with after nearly 9 months since the bomb and 6 months of struggling to DB is that ultimately, we can't really fix this, but we really can screw it up by not DB'ing.
