I'm on the same page as the rest of these guys, Made. I'm so sorry to hear that it's gotten to this point for you. I'm also sorry that your messed-up W has created this huge tornado of destruction.
I have a very strong feeling that she knows exactly what she's doing to you, both of your families, her friends, and herself. She probably really hates herself and wishes that she hadn't done what she did, but she still clutches onto this path because it's far easier for her than cleaning up the mess she made.
My advice? Step far away and let her roll and bounce like the human pinball that she is. Maybe she'll come to a stop eventually, but you have no reason to put yourself in her path anymore. Like so many others have said, only she can solve her problems now.
Made, I also have to say that you're a total inspiration at how to handle life in the wake of being ditched like this. It sounds like the academic, professional, social, athletic, and religious spheres of your life have really begun to explode with life. Even if your W seemingly doesn't want to have anything to do with you, I can guarantee that there will be other women out there who will want to marry you in a heartbeat.
The song that you heard at church seems to be the Big Guy trying to tell you how to move on from this. Rather than bemoan the "loss" of your W and M or make immediate plans to find someone else, just let God take your life into his hands. Keep walking down your path and be open to whatever He has planned for you. Chances are, you will eventually find yourself in a much sunnier, greener place that where you are now. And you will undoubtedly be a much stronger and wiser MTS as a result of your struggles.
