It sounds to me like you are reenacting your mother issues. You are attracted to people like your mother. You are trying to work out those childhood issues. You are looking for someone like your mother to "end the story" a different way. You are trying to earn NPD's respect and love.

Then, when you are with "normal" people, you reject them. You essentially become your mother and devalue them. People unlike your mother are not attractive to you. They do not have your respect. You may consider them weak. Have you heard the saying, "I wouldn't want to be a member of any club that would have me as a member?" You may dislike yourself so much that you can't respect people who like you.

Again, I think this has a lot to deal with resolving your childhood issues.
