He feeds off my guilt, and says that any guilt about you leaves a bad taste in his mouth. Perhaps that's his way of extending the olive branch, and it certainly is some way of making sure he will not be a part of my life - or yours - any longer.
I cannot apologize enough for my attitude towards you. I have destroyed all trust you have in me. But know that I have seen the error of what I had done. I cannot excuse my behavior. But I can assure you it will no longer happen. I know that I do not deserve your forgiveness, or the forgiveness of anyone else.
I care now for you, as much as I ever should have. It is that care I have for you that compels me to confess my pains of the past.
