one more thing to add:
The couple of months before she left, we had begun to get along really well...better than we had in many years. Looked like things might be heading in the right direction. She was in a mentally taxing online class the week before she left, and had been REALLY stressed about her career and job hunting. I knew she needed a break and would probably go visit relatives south for a few weeks with the kids, which we did every year in summer.
I read 'how to survive your wifes midlife crisis' and her pattern of behavior fits exactly...from telling me I love you, to acting sweet one day and distant the next, to suddenly running without thinking of the consequences. She's like a completely different person right now, totally indecisive, lost, confused. I'm not making excuses for her, just trying to figure out what's best to not push her away further. I'm wondering if she came back home, what suddenly being back here around the memories, the home, etc. that she'd made up her mind to leave...what that would do to her?
When the kids arrive today to see her...will that make it hit home for her? Nothing? Trigger something? Help her move to the next MLC stage? I read in Divorce Remedy something about guilt or anything to bring WAW home is at least something to help on my behalf....not sure how it was worded.
I mean, she ran to a place where there are no reminders of this house, me, our marriage, the kids, nothing. She would have a new job, new place, and in a new environment.
Seems like the ideal way to escape for her huh?

I just wanted her to see the consequences, and know what my decision was going to be if she stayed. I NEVER expected her to suddenly change her mind to 'I'm coming back with the kids' and I'm aware that could change again.
What's painful is that I know she loves me, and I know she'll pass through this someday and might realize it.
