While Tate has consistently tweeted about the season, Rousey's Twitter feed is chock full of posts about Bulgaria and Instagram.
"There's a responsibility to represent female MMA that comes with being the champion, just as there's a responsibility to represent and promote the show when you coach TUF," Tate said. "It grates on my nerves that Ronda isn't promoting this season, which fans are saying is the best for a while, because that's what we as established fighters signed on to do: to share the spotlight with these fighters who desperately want to join us in the UFC.
"No one would have turned down a Hollywood movie without giving it a lot of soul-searching, but surely Ronda could do phone interviews or at least tweet about TUF. They have cell phone reception in Europe, don't they?"
Tate also says that during the filming of the show, she learned that Rousey is emotionally unstable.
"People have asked me what I've learned about Ronda from doing TUF with her. Basically, I've learned she's a lot more emotionally unstable that I ever could have realized if I didn't see her day-in, day-out for six weeks," Tate said of Rousey. "I've learned that I can work her from a different angle, from a psychological angle.
"I've never used 'psychological warfare' in my career before. This is an unexplored aspect of the sport for me. I've never tried to get an opponent crazy or emotional on purpose to mess with their preparation or distract them. I know Ronda tried - and to a point succeeded - in making me emotional ahead of the first fight. She has said that's how she beat me the first fight."
Tate says Rousey has gotten more emotional in recent months, now that "Cupcake" knows how to handle her mentally.
"However, now I've left that anger, that dislike of her behind me, she can't affect me emotionally like she did when we fought in Strikeforce," Tate said of Rousey. "And what I think is happening is that because she can't have this effect on me, it is almost like she's become more emotional instead. I didn't go into TUF wanting to make her go crazy, to cry all the time, to get furious and scream all the time, but that's what happened. I think it is a huge mental victory for me ahead of our December 28 fight to know that, one, she can't get inside my head anymore and, two, to know how fragile she is emotionally."
