Spent last half hour reading this thread.... PFM at it's best, although some comments perhaps best overlooked given the sensitive nature.
I disowned my father, largely - not totally - but enough that contact was at best minimal, often long periods of nothing. I left home at 16, as I couldn't handle the fact he was a serial womaniser, my mother being constantly upset, her regular "falls" and broken noses/arms and such like, and the beatings I got for my behaviour. I was no model child (or a model adult for that matter), but the fear of being caned at school, and then going home to be belted by my father deeply affected my teenage years. I was forecast 9 Grade A 'O' levels but I royally messed it up and left home at 16 with the clothes I had on...
My relationship with him was better when I didn't live there, but there was little healing. My mother finally kicked him out when I was 22 and he was shacked up with some random woman in a bedsit when he died suddenly of a heart attack. I have had huge guilt issues in the last 30 years that we didnt at least "try" to make amends, listen, learn, communicate. It just happened and that's that.
Never really put down in words any of this, not sure why now. Anyway, there we are.
