Rihanna opens up in the latest issue of Vanity Fair about her non-existent relationship with Chris Brown and why she ended things the second time around.

Check out a quote from the magazine:

“I was that girl… that girl who felt that as much pain as this relationship is, maybe some people are built stronger than others. Maybe I’m one of those people built to handle s*** like this. Maybe I’m the person who’s almost the guardian angel to this person, to be there when they’re not strong enough, when they’re not understanding the world, when they just need someone to encourage them in a positive way and say the right thing.

I was very protective of him. I felt that people didn’t understand him. Even after … But you know, you realize after a while that in that situation you’re the enemy. You want the best for them, but if you remind them of their failures, or if you remind them of bad moments in their life, or even if you say I’m willing to put up with something, they think less of you—because they know you don’t deserve what they’re going to give. And if you put up with it, maybe you are agreeing that you [deserve] this, and that’s when I finally had to say, ‘Uh-oh, I was stupid thinking I was built for this.’ Sometimes you just have to walk away… I don’t hate him. I will care about him until the day I die. We’re not friends, but it’s not like we’re enemies. We don’t have much of a relationship now.”
