He is correct, as the relationship is going to end badly, especially with a woman who is extremely jealous, suicidal and taking hard drugs. Brown's dad would have rather he date singer Jordan Sparks, who he says is a nice, wholesome girl (codeword: Rihanna's been around the block too many times).
Brown's dad and most people in the industry also prefer his on and off girlfriend Karrueche Tran, as she is nice. Brown's father said she is sweet and has manners. However, Rihanna has a reputation for being rude, arrogant and evil to people, without provocation. She believes her hype. Many fans view Rihanna as Brown's downfall, stating he'd never had a domestic violence issue prior to her, but she had fist fights and bottle fights with her siblings.
As stated previously in the column, the Judiciary Report is of the belief Brown and Rihanna are soulmates, but their relationship is so damaged and scarred, with repressed resentment, they are going to have one horrible time trying to make things work. God brings people together, but some people mess it up with bad choices and end up regretting it.
