I love the show and love the brand B has "created" but you deserve incredible props for being such an anchor. B is very manipulative and self-serving, even in her displays of generosity. You clearly made the best decision, though it must have been extremely difficult. I hope when her brand expands and maybe one day has stock options, that you get a share of the company. It would be the thing to do. B clearly was trying to hurt you regarding the way she spoke of putting Ra Ra in her will, and in the manner her blog was written. She no doubt feels betrayed by you adn it really appeared to an outside viewer that while she said she wanted you to do what was best for you, it seemed to me she wanted what was best for B. I don't know what kind of financial arrangement you all had or have, but if you did not get a several hundred thousand dollar bonus... at the least, that would certainly speak volumes.
AT any rate, you helped make the show and brand what it is and there is no doubt incredible life ahead for you.
