For Rohag and Fuzzy, you may feel more involved/responsible for your parents' dysfunction because you were the only children.
I am the youngest of three, and don't feel one bit involved. That's not entirely true, now that I think of it, I remember a time where she was screaming at him for not doing something regarding me, and I felt like if I didn't exist, they wouldn't be fighting.
But for the most part, I recall my mom screaming at my dad over money, politics, his bast*rd father, etc... so I didn't feel responsible.
I did not think we were dysfunctional honestly until a few years ago. And I know my mother must have disorders. My father took the easy way out- death at 44.
Because I witnesses my mother be abusive to men, I blame that as it having rubbed off on me. This is the cause for my depression. I can't have a good marriage. Bad role modeling. I'm a broken toy.
And as for emotional neglect, I wasn't allowed to have feelings, if they weren't my mom's feelings. Yes, she's a narcissist.
