I agree with this.
I often feel as if my father never liked me, but how can someone not like an innocent, sweet and vulnerable child? I think the truth is, for my father and yours, is that they never liked themselves.

Your father's striving for perfectionism was most likely an overcompensation for his own flaws. But that perfectionism may not have alleviated his struggles with them...he could find an external source for his anger and a comprehensible way to displace it in you...thus you were most likely the scapegoat for his own failings.
Parents often try to live vicariously through their children (thus setting very high standards) to achieve things they were never able to. Your father expected perfection and (because he was far from perfect) would direct his dissapointment at his imperfection onto you. I do not think honestly, Mr. V, that you were rejected because you were 'flawed'...there's nothing 'flawed' about you...if there is well, we're all a bunch of 'flawed' humans making mistakes and blundering through life.

I think your father may have had very low self-esteem and wanted to alleviate it vicariously (that's where you come in). Unfortunately, you're now left to pick up the pieces...I'm so sorry

I've experienced similar feelings.

Either way my insect-loving friend. Anyone can be a parent...cockroaches breed afterall. Sometimes I think they make better parents than people.
Much love.
