I found that having absolutely no contact with AH for the first couple of months was absolutely necessary for me to begin my healing. I would not have done as well if I had to listen to his pleading, anger, whining, whatever.
One other thing. If you are now finding that giving him a ride is too difficult for you, you do have the right to change your mind effective today and tell him to find another ride starting tomorrow. You have the right to protect yourself, your emotions and your overall well being.
