The Narcissist
He doesn't like your dog? Do we even need to talk about this one? Put it at the top of the category that includes he won't make eye contact with your kid, he doesn't want to meet your sister, and he whines the first time you make plans with your girlfriend. A man threatened by the love you have for the dog you sleep with is going to be threatened by more things than you can name. Dating him is inviting the type of conflict into your life that will make you tired before you even get up in the morning.
