Five easy pieces

I think that one of the main struggles that Robert dealt with was brought up by Catherine, when she told him that he couldn't love anyone because he had no love for himself. The whole movie it seemed like he was trying to fill some sort of void, he was never content with his girlfriend. He was always trying to find satisfaction by getting with other women but it seems that after he was with those other women he ended up being unhappy. I think that the lack of self love came from his relationship with his dad, it seemed that his dad was upset that Robert didn't follow in his footsteps.
