Bite the bullet. Get out. It's not optimal or prefered, but your W seems pretty clear on where she is. If you think you can approach her about her moving out rather than you without blaming/accusing/guilting her and having that conversation in an open manner, give it a try.
Gotta disagree pretty strongly with you here. IMHO, the MLC Gang ALL "seem pretty clear" on what they want - everybody get on board the crazy train, let's all just cave in and agree the M is over and there's no hope, hurry up and get that D as soon as possible so I can move on to my wonderful new life without you.
The heck with that alien spew. If someone moving out is such a great idea, point her to the door and let her do the hard, painful work of ripping her life apart.
