I understand Tickled.
In my case, my parents are who they are by background... my mom being eldest of a large family became the caretaker for her siblings and that carried onto her relationship with my dad, him being the youngest of a large family. They didn't know how to give love except through caretaking because their parents were too busy raising huge families to give loving attention to each child. Mom was methodist and Dad ex Catholic when JW's knocked 'em up just before WWII. If they weren't JW's I don't think too much would have changed. Except that they adopted me because they knew my grandmother from the congregation, whom my birthmother was living with at the time.
What's sad in so many cases is that people are who they are, and so much blame is placed on other things and issues, and the source of the problem goes on deeply hidden and never dealt with.
