I don't ruminate over anything she said or did anymore. Those days are over.
But there is something that has boggled my mind ever since it happened. From time to time I think about it and wonder What the heck that was. And I can't come up with ANY explanation.
So feel free to come up with theories!

Let me first set the scene. She had broken up with me via letter that she left on the bed before leaving for the week (business, but who knows.)
I don't have to go into details about what a blow this was, although things weren't great (ST, constant berating etc.) but I had never expected this to happen.
When she got back I still had hopes, we had only married two months prior, right?
It wasn't all bad. From time to time we actually had pretty good conversations about us and her. They seemed to be genuinely open. Although she sometimes cut them short and went to the bathroom, where she spent most of her time back then. While I was sitting in the living room suffering, with so many things I had to say. But I wanted to respect her need for space (she wasn't doing well, a close friend had just died in an accident on top of all that.)
Anyways. There was a situation, we had just talked and she went to the bathroom. I walked behind her, through the bedroom. Just when she was about to step into the bathroom, I said "hey... ." and wanted to just close the conversation we had before by saying something nice, like "if you need anything I'm in the living room" or whatever.
She turned around and before I could get the words out of my mouth... .
She grabbed my by the throat. I was stunned. It was a firm grip, but not in the sense of assaulting me. She just grabbed me and looked me deep in the eyes. She had this smile on her face, it was weird... .really, really expressive. Don't know how to describe it though. Dominant, but not necessarily in a threatening way. Kind of flirty. It somehow, especially in retrospect ,felt sexual on some level.
It was just for a bit over a second or two. She then let go, turned around and went into the bathroom, leaving me back absolutely puzzled.
She had NEVER done anything like this ever before. It was so out of context... .it's puzzling me to this day.
Like I said... .Not ruminating, it doesn't really matter. But it was so elfin weird that I'm really curious.
