Beagley ... new to your sitch but something you proposed struck me.
Problem with the 50-50 stat .. thats out of all marriages right? So people who come here obviously are more towards that 50% D group already as more than likely the WAS is already checked out. so out of that 50% 'doomed' number ... who knows what percentage truly DB and save their M .... but even if they do not, and there are a few vets here who fall under that category ... the lessons they learned have helped them with the second M, while the WAS might be on marriage 2, 3, 4 .. who knows.
For me, DB not only saved me .. but I honestly am one of the few who might just walk through this mess and save my M, almost 2 years of separation, but my W and I are slowly working on our M. I will tell you with out hesitation ... you have to save yourself first, without that, my W and her A would have been history but she would have kept looking for a better option, it took alot of work and a TON of help from the wonderful people on this board, I learned more from others threads and advice they recieved than I did on my own sitch/thread
I will steal a line from Retrouvaille ...and apply it to DB, Try DB, go through the process.... do the work, I mean really do the work ... and if you do not like the results you can have your old relationship back.
My advice , listen, do the work, take the advice, be patient ... your M did not dissolve in a month, nor will you save it that quickly.
