Hi. I'm reading your sitch but again nothing much to add. It's absolutly crap and knowing at the end of this you will be happy again is little consolation right now.
I found the harest part was accepting that W did not want an R with me anymore. Even though she still ( over a year since BD ) says she's not sure what she wants and isn't happy
It takes time to accept that the M is over and that's not to say a new M is nt possible one day but for now it's over
Stay strong and keep DBing because it does work for every one. Maybe not to restore your M but for you as a person
