I know someone married to a guy who won't brush his teeth.. Has many cavities and avoids the dentist because he is embarrassed about it. He doesn't shower for days. She won't kiss him when it gets bad but he shrugs it off and says "fine". She's threatened to leave and supposedly there's been improvement but I know he won't keep it up. And guess what, he's morbidly obese! I believe this story completely.
