My ex left me just before the birth of our beautiful ds. Although he contacts us occasionally we haven't seen him for four years and ds has no memory of him. Now he sometimes cries because he doesn't have a dad. I think he feels this more strongly now he has started school and finds that he is the only child in his school in this position. I've asked my ex to visit so many times but he always has an excuse not to come. Is anyone else in this position? How do you cope?
