ENTP Relationship deal breaker, basically: I'm screwed. (Follow the link for the other types too! They're accurate.)
Myers-Briggs Indicator Personality type ENTP (Extrovert-Intuitive-Thinking-Perceptive). I don't consider this a problem; more a point of interest. I've often wondered how I could be an extrovert when I enjoy spending the majority of my time alone.
