JR, I've had the same thoughts recently. That maybe it's just so far gone that nothing I do will bring my M back to life. It's depressing to think, but may very well be the case and if it is I'll just need to accept that.
With that said, the old M may be DOA and not revive-able, but that doesn't mean a new M can't grow in it's place w/ my W. If us LBS's can rebuild ourselves into better people then there's at least a glimmer of hope. And, if worse comes to worse, and there is no new M to rise from the ashes, at least we are better parents for our kids and better prepared to succeed in future relationships.
It seems like there is a positive outcome to be had, regardless of how the situation w/ our WWs works out. All comes back to focusing on ourselves and making us better people. I figure to get to that point, I need more time than I've put in so far. May as well fight for my M, via DB'ing, while I work on myself at the same time.
