I don't feel you are completely off the mark, to ask.

Sometimes parents seem to go through the motions, sometimes parents themselves don't know how as human beings to be close emotionally, in general.

I'm not sure if you've ever considered checking out the Psychotherapy Forum, on PC, not to say you, yourself would need therapy, but to guide you to a group of individuals, that have excellent discussions about 'attachment' theory. Not that the Relationships and Communication Forum isn't also a forum to post in, just my hunch senses that if you were to copy and paste this post there, you may actually find extra added insight, that may help?

I'm sure you'll get insight here, too. I'd just read something there, that made me think of your post.
