Well I'm definitely not a professional....very very far from, but I can tell you what I think.

My husband of four years has a personality very much like that. I used to tell myself that maybe it was a quality of a man to be cold in situations where a chick would be compassionate or sensitive. But eventually I realized it was more then that, that his anger and coldness was beyond men's nature.

What I've concluded with our situation is that he has developed this coldness, hardness, and nothingness to deal with life. This is his way of suppressing his frustrations, compassion, and sensitivity. He was severely abused and neglected as a child and I believe this was the way he adapted to his life at the time.

I'm not sure if this has anything to do with you or not, but from ^ up there it sounded much like my husband.

I'm just blabbing nonsense hoping I'm saying something beneficial......hopefully I said something that made sense....lol.
