Dr. Susan Weitzman is a psychotherapist who specializes in emotional abuse and the author of Not to People Like Us: Hidden Abuse in Upscale Marriages. She says that emotional behavior like Kim's and Eddie's is often kept a secret because the two usually have a "silent agreement" about the abuse.
"First, [the woman] buys into what the guy is saying," Dr. Weitzman says. "She buys into [the emotional abuse], and it's like a systematic erosion of self-esteem. He says she's bad, and she says, 'I guess I am.' Ironically, that bonds them in some crazy kind of way. They both agree that it's her fault. There's the feeling of being ashamed and embarrassed, or maybe she's hooked on hope, as I call it. She's hoping he'll change so if she doesn't talk about it, maybe it will go away."
