I'm so sorry it's come to this Markline...
Personally I believe the stigma lies on the one who walks away from the marriage and will not consider repairing it at all.
Anyone who knows you (including yourself) should be quietly told that it was not your choice (I'm purposely not using the word "fault") but hers.
If I were in your shoes they would have to divorce me. Do the work themselves, pay the court costs. I'd also see a lawyer (if you haven't already). Do NOT share a lawyer no matter how much "easier" you are told that would be.
Once again, my heart goes out to you... You have every right to feel devastated.
A small voice in your ear for the future?
Please watch the level of bitterness & how deeply you allow the cynicism to get.
They are more corrosive to yourself & future relationships than to the person you were hurt by..
Hugs from cyberspace to you,
