It behooves you to USE your L and remove yourself from 'negotiating' with W or attempting this DIY stuff. Call in the pros and let them handle the legal stuff. You've already instructed your L to drag this out as long as possible and s/he will do it for you.
Really...you've got to stop engaging in emails with W or trying to do this DIY stuff with your W. It gets you nowhere and puts you in W's crosshairs. Ineffective...no? Right.
I do not understand why you persist in this fruitless endeavor when you've been advised to step away from DIY and getting a new L. Let's face it: we're not Perry Mason here.
