I saw a video by I think Mindsmash (great channel btw). He talked about how Ronda is very insecure deep down inside and because of that, building her confidence back up, would be pretty easy for any decent coach.

Other sources said, that she is probably attracted to the fact, Edmond completely dismisses her, because that is the only feeling she knows from people who should have loved her in her childhood(this bleacherreport link: http://bleacherreport.com/articles/2684160-is-ronda-rousey-broken-or-ready-to-roar-back-her-past-may-offer-some-clues)

Now taking that, looking at this video, and I'm sorry if this may sound stupid, but she just looks like a kid, sitting next to her dad. The way she acts, her body language with Edmonds arm around her, it's like she feels save there, even tho she is a uncomfortable with the camera's around...like he is holding her hand.

This is why I think she is not leaving Edmond. Not because she is super stubborn, or blind. I think she just found someone who loves her like she is used to. Like she was treated her whole childhood. His dismissive hostile way of treating her, she probably doesn't know any better.

But hey, that's just me speculating.
