This is a continuation of the thoughts from my last post here. I really appreciate the replies I got there from you guys.

My wife has always had PMS issues, and may very well be BPD or type 2 bipolar. But the oddest thing she does is this; (does anyone know what it's called?). Late at night when everything is done, the pre-bed routine is finished, and we're under the covers, we're tired and it's time to finally say "Good night" - we both seem in a good mood - she gets argumentative. She'll pick some little problem which she percieves as my fault and just start harping on it. And when I seemed to have resolved it, she'll jump to something else. And there may even be some delusional things like thinking that I'm having an affair or hiding money (both totally untrue) and sometimes it may take an hour or two before she peters out and falls asleep.

I'm sick of this behavior above all else. Has anyone else experienced it? It's like an overtired baby who can't fall asleep and stays cranky.

What if I were to put on my pants, grab the car keys, walk out and spend the night at my father's house? (Mom RIP) And make it clear that I'm contacting a lawyer the next day? Maybe even text it when I arrive at my dad's house?

She actually has said during these late night arguments "go ahead, if you don't like what I'm saying, get out".

I'm in a no fault state. We have 2 teen daughters at home (17 and 14) Because I walked out (even though I notified her of legal intentions) are there any consequences for this?

I realize the "proper" way I should contact a lawyer first and serve the papers during the day, but by leaving during a late night argument, I want to make it clear to her that her behavior is unacceptable and this is the cause.

But are there any legal consequences that I "abandoned" my wife and kids? Thanks again guys for your help.
