Painful.
Jeff deals with some of, with the possible exception of Troy and Annie, the most awful, self centered, ignorant destructive characters in television! Yet, after every betrayal, every selfish manipulation, crippling humiliation, personal and mental violation, the lies, abuse and constant dismissal of his actual thoughts and feelings for their own, he forgives them.
He not just well adjusted, he's a saint. He would be phenomenally better off with as much time and space between him and his viscous abusers as possible. Yet, the circus never seemes to end. He just coming back for more punishment.
