Who changed?

Maybe I got this whole thing wrong. 
This whole time here I was thinking that you've changed.  That you are no longer the person I used to know and care for.  That you had somehow become this person I just can't stand.  But what had never crossed my mind was that maybe you've always been this way.  Maybe the person who changed wasn't you....it was me.  And for the first time I am seeing you for who you truly are because I am no longer blinded by the person I used to be.  And I'm coming to realize that I really, really don't like you.
