My (future ex-)wife is the same. She says she loves her 3 children more than anything, and she misses them when she's abroad for work, but still, she chooses not to be with them.

Either they love their work more than anything, but don't want to admit it, or they love their children but don't feel the need to be with them as much as any other person.

Maybe it was a mistake for such a person to have children.

Sorry if I sound too harsh, but being recently in the same situation, but on the other end, is pretty rough :(.
