I think this week we basically got to see why Ronda has all this mental baggage. It's basically how her mother treated her as a child. It seems like her mom didn't hug her enough. It seems like she was extremely tough on Ronda, and basically Ronda admitted that she grew up feeling that her mother didn't have a heart, aka her mother didn't express any love. She says she understand now why her mother put her through all that hardship and even made her fight injured and all that... but clearly Ronda worships her mom and keeps working for her approval. Even being UFC champ doesn't erase the insecurities inside Ronda because her mother basically tol her she's not going to be good enough for her mother, no matter what.
