Hey lostrig, it sounds like there's a lot more to your sitch than you've shared with us.
The communication issues jump out at me, especially with the way fights seem to pop up out of nowhere.
She's probably taking it out on you. It sounds like she's mad at herself (maybe for something she thinks you "made her do").
Has there been any other discussion of why she wants this, other than what you discussed in your initial post?
Holding, not really sure what more I can share to enlighten the sitch. I can tell you you this is my W second marriage. Both my W and I tend to bottle up our emotions until they reach a boiling point. We don't argue much but when we do it all comes out.
Most of what she is telling me now as to why she wants out is that she in miserable in this M and will never be happy married to me.
