If she file, how is dragging it out going to help. I think it will only make matters worst and make you look desperate.
There are times when LBS's are done and they file. Just make sure if you file, you are not doing it to get a reaction out of your WW. You are filing because you no longer want to be married.
If you want to work for recon, then, don't file and DB, become AMOAFWL.
There's no hard set rule, instead there are a bunch of concepts that help you figure out what you want and need to do for your future. DB is a way to save your M, but this forum is here to help you save yourself. This forum helps you regain your logical mindset and sanity to make sound and rational decisions.
If the sound and rational decision become filing than, you can make that decision in a clear minded and loving way.
