So FF, what is more important to you? Your marriage or your money? Both can't be the priority. If you say the money then yes sign and move on. If you say your marriage then do not sign.
Personally I would continue doing what you're doing. Have you stated to her that you are against the D, will not sign the papers and she'll have to move forward with a contested D of that's what she wants? Make her realize this is going to require effort and work on her part. Next time she reaches out make sure to tell her that.
But let her reach out. She created limbo not you. You have every right to fight for your marriage. Just be aware that if there's what she wants them that's what will eventually happen. Let her go to get her back. But make her do the work on the D.
