Hmmm... this explains a lot about a college boyfriend I had. Spent the first 4 years of his life in an orphanage in Korea before being adopted, I don't think he had a lot of nurturing contact. Inability to connect emotionally, I felt a weird lack of compassion from him, like something was dead inside. He's got a kid now, I hope he was able to work through some stuff.
I was very lucky in that parenting respect - very nurturing mother, and grandmothers took care of me during times when she was working and couldn't.
