Emotional abandonment.

Perhaps not the best writing skills, but I definitely relate with the sentiment.

Although, the longer I am moving through the divorce process, the less I trust people who seem to know who my wife is, or why she acts the way she does. It is so hot and cold. And it's always been that way for the two of us. The difference now is that the swings are much more exaggerated, and the cold overwhelms—BY FAR—any warmth. But after being partnered with her for 12 years, I still can't really explain what makes her tick or why she shuts me out. I wish I knew, because then maybe there would be a solution.

I do agree, though. It's not even being shut out sexually. It's the emotional and empathetic abandonment. And the persistent feelings of rejection that come with it. I feel I will be dealing with those for a long time.
