Just wanted to send a note of support. The D process is so draining on so many levels. Hang in there. Glad to hear that you have found a greater degree of independence and self-contentment over the last six months. Good for you.
I know what you mean when you say that you may not want your W back and that you're not sure if you could ever be in a R with her again. I have felt the same way during my S. FWIW (I am a DB newbie), be present and take it one moment at a time. If the D happens, the work you have done on yourself has put you in a position to engage in a loving relationship in the future. If you and your W are able to reconcile, the man you have become will make for a better M. Continued good luck and best wishes.
