Awww Marjan, be strong, I know how you feel. He is not worth it, and you are doing a good job by avoiding him. You may need to delete your gmail account or stay away from facebook. Don't give him that much power. Its been about two weeks for me and I feel good since I ended things. You can do it too. Put all your focus on taking care of your sister. Take care of yourself. Hang in there!
