The Daily Beast has an interview with the actress Yolonda Ross who plays Robyn in the film:
I have to confess, I had no idea that Whitney had a rumored gay lover before reading about your role in this movie. No clue!The movie debuts on the Lifetime network on January 17, 2015. But because this movie doesn’t actually go out and say “they were lovers!”, how do you portray their relationship? Were you playing up or, on the flip side, shying away from portraying a romantic attraction?No, I wasn’t shying away from it. She’s a beautiful woman. And from what I knew of Robyn then, I don’t think she was in the closet. It’s a love and it’s an admiration. So that was played there. How much of it is a love that’s between two lovers is a different story, because that, then, would have called for there to be different kinds of scenes in the movie. I played it as love and longing. Ultimately, what’s happening with them is that the person who Robyn loves is leaving. No matter if you’re lovers or a best friend, when someone you love leaves to get married, your relationship is going to change. That’s what I played. And that’s what it was.
