ST, It really doesn't matter what your wife is you still DB the same. Do not pursue, beg, plead, etc.
That said, the major difference from my understanding between a WAS and a MLCer is that a WA will plan for the event. They will save money, look for place to live or plan for you to have a place to live.
MLCers show confusion about it and some just up and walk away without thought to consequences or how it will affect others. They have no real plan. Depression is also a big factor for the MLCer.
