Really feel like there is no way this will change. I struggle daily to resist the urge to file as a last last resort technique. I fear this is the only way my WAW will change.
You should never treat something as serious as divorce as some sort of DBing tactic. Even the AFTER-the-Last-Resort-Technique doesn't necessarily include filing for divorce.
Filing for divorce should be a legal, financial and even spiritual decision that you only enter into when you've tried everything else, in my opinion.
