I can kind of understand this a bit...I've seen and know women who show up when they're other half is going out for a guys night and do the same thing, walk over to the table and say "hey, what's up". So I can see how something can escalate from there or why a guy would say don't come to this place I'll be at tonight. To me, respect is lacking, on both sides, if you have to tell someone not to come to your guys/girls night out and if the person shows up anyway.
Chis grew up with a very skewed view of the dynamic between men and women, I'm not excusing his behavior obviously.
Except she wouldn't have known where he was going to be unless he'd been talking with her. In which case he was still keeping in touch with his supposed ex. And the other woman had sent him a text earlier telling him she would be there. If he was too dumb or too drunk to check his phone before handing it to Rihanna, that's on him. I still think he's deflecting in this interview to try to make himself look better about the beating after all these years.
