This may or may not be typical?
If I don't know you, I can see a spectrum. I have three categories people can go in. I either like you, don't or I am indifferent. Switching between these, after first impression is pretty difficult. After I get close to someone, I split them into how they act. When they are being a bitch, I split that off as the "other"... its almost like another person all together. Then I can treat the bitch version really awful, because I hate that one.

I know this makes no sense, and I have gotten better about it lately. Well... :/ with some notable exceptions.
So when a person is being mean I hate them; when they are being nice I love them. I see people in one of two ways: They are either acting nearly perfect with very few or no flaws, their smile breaks the overcast clouds, pouring sun rays down on flocks of bare-bootied cherubim, singing merrily with harps. Their voice is 1000 baby fairies, dancing capriciously on bells and their presence is the essence of comfort, peace and love. Or they are the most self-centered, reprehensible, vapid bitch on the planet. Just looking at their evil face makes my skin crawl. Their mere presence in the room with me is enough to make my anxiety start going through the roof. Proximity -or worse even, touch- incites instance fight or flight reaction.
Switching between the two is fairly easy for other people. Do something extraordinarily nice when you are split black, or something awful or invalidating when you are split white.
I developed this really strange coping mechanism during a long distance relationship. Whenever she was in person, she was wonderful to me: ~Dream Come True~

... Whenever we were on the phone she was psychobatshit crazy. She acted like two different people, so I treated her like it. Thus began the most maladaptive coping mechanism I do. I see black and white, rather than black or white.
