It sounds like both of your WS WANT you to end it... They want YOU to make that decision. They seem to think they are saving some dignity by NOT ending the marriage... They are Ok with beating it to death with a stick, but they won't deal the killing blow... they cringe...
If you want my advice, just live your lives outside of theirs but don't file for a D... Show them what commitment means.
D is just a piece of paper, why does it have to be filed to live a full life?
I would hold onto your marriage, protest where you can, but otherwise live a full life maintaining commitment... keep up the protest and exposure... These cowards will have their day...
