2old, chances are that she said something to you regarding the M. She may even have given you hints that she was done. She either didn't express in a way you understood or you weren't listening. They don't just pick up and go. There are hints. Some we catch some we don't. She may have made it perfectly clear but you were in denial. I don't know, just making assumptions.
The bottom line is that you are asking questions that only she and maybe you know the answers to.
The more you dwell and obsess the harder this will be on you.

I can tell you that I noticed changes in my Exw's behavior towards me in 2009. We separated in 2011. I don't think there was anything I could have done about it knowing that. Gal buddy and gal hard.
