If this was the case, is there any way I should communicate to her that it's not too late and I would give her a chance if she repents and turns away from her destructive behavior?
Sorry, just saw your post above. Here's how I see many LBH'S. They are much too eager to assure their WW that he doesn't want a divorce, and that it's not too late, and he will forgive if she'll just ......
I think I know what you are thinking. You are afraid she'll believe it's hopeless and you won't take her back. So, you want to assure her that it's not.
I don't think you need to tell her, especially when she has shown no remorse.
I don't think it is highly unusual for the WW to hesitate or not respond to the lawyer or proceed with the agreement. Could be out of spite or she may be just be mulling it over in her head. Who knows?
Don't tell her anymore that you don't want a divorce. She knows it. She has to go to you. She has to be ready. Telling her that it's not too late can be pressure.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
