Another light bulb moment about my father

I just had another light bulb moment reading one of the links I just posted.

When an abusive man/partner knows you are trying to leave he will get very angry because you are seeking independence away from him.

I just realized this is the same reason my father got so angry when my sister wanted to move overseas, and why my father also did the same thing to me (despite the fact I was over 30). He'd tell both of us that we couldn't 'make it' etc etc which is similar to an abusive partner telling his wife that she's worthless without him and can't 'make it' etc. So over time she begins to believe this shit. Because if we left, he would have noone and nothing to control anymore. And noone to possess or obsess over.

Aahh...
