My therapist help me see that about me, too. My parents always fought and often made me feel that I was the reason. My father, several times told me, "The only reason we fight is because we disagree about how to raise you." If I did things my dad's way, he would be pleased, if I did things mom's way, she would be pleased. They also talked about each other, behind their backs to me. I ended up learning to be an emotional chameleon, trying to whatever my parents needed me to be in order to get their approval and stop them from fighting.
In relationships, it meant, for me that I could never be honest about my desires or feelings with people. I could seldom achieve intimacy.
