Have you been giving people more "benefit of the doubt" action than usual? Im sure you do this often when dating too ? You know what it actually is... the potential vs reality. We tend to imagine how great someone is or could be because we know they are capable of it. We ignore what they are doing in "real life" because our vision/ideas of them are better. Guess what?! He is not who you want him to be and until you understand that you will continue to be disappointed.
