You really need to STFU for real about asking W questions about filing or not filing for D. It DOES NOT matter what she does or does not do. You have a FULL and rich life waiting for you to grab it by the horns.
For real, you have to STOP bringing up the M or divorce to W.
Of course that is if you are still trying to save your marriage/relationship.
If you want to be divorced then just keep doing the same thing.
