He is apologetic, sympathetic, but most importantly, he regrets leaving you and breaking the bond you two have formed in a span of one year. He believes that everything is his fault and while that may be true in this case, he even faults himself for his fear of being touched. He loves you deeply that he thinks you deserve better than a lowly man such as himself. He never forgot about you and thought it was for the best that he was no longer in your life, he was wrong. He fears touch.
