Believe his behaviors and patterns, NOT his words. Trust me, it's a hard lesson I had to learn myself. But he has given you ALL the clues necessary that tell you he cannot commit and won't commit -- he has point blank told you he runs away from every relationship, that he gets bored and restless. These are all HUGE RED FLAGS. Therapy, if he agrees to this, will take a long time for him to work out his problems. Are you willing to wait or even stop seeing him while he figures it out? I doubt it. If I were you, I would take the cues and walk away -- no matter how you feel about him and no matter what words of love he uses or empty promises he makes. Behavior patterns speak VOLUMES far louder than words and are to be believed and not excused or dismissed. I would walk away. This is not a good prospect for a longer-term commitment or relationship.
