Up until recently, I was among the people who hated reality TV. And there are some shows – like the popular one about a family of attention whores and the other about a group of women who used to be married to or date athletes – that are fairly pointless as anything but guilty, mindless entertainment. But a closer look at some of the shows provides something surprising. On shows like “Love and Hip-Hop” both the New York and the Atlanta version, there are a host of relationships in turmoil. Whether it’s Chrissy Lumpkin infamously vying for a ring from her longtime boyfriend, rapper Jim Jones, or Emily B.’s incomprehensible commitment to a man who doesn’t even claim her, there are cautionary tales to be learned from.
