Ex-etiquette: Son doesn’t want to leave home

Q. My son is 9. His mother and I broke up a year and a half ago. Although we absolutely do not get along, we have been trying to share his time. We exchange every few days. Each time he has to leave my home, I see the happy little boy slip away. Sometimes he tells me he doesn’t want to go, but he can’t tell me why. I told his mother, but she doesn’t believe me.

Ex-etiquette: I think my son is too young to go online. My ex disagrees.

Q. My son’s father has only come back into our son’s life in the last year. Prior to that he lived in another state. Our son likes to talk to his friends in a social media chat room site, but I do not want him online unmonitored. I believe he is too young and when he does go online, I require him to give me all his passwords so I can monitor his activity. His father allows him to go online at his home without monitoring. I have told his father I do not agree with this, but he says at his age, our son needs his privacy. Our son is 11. What’s good ex-etiquette?

Ex-etiquette: How can I apologize after I hurt her?

Q. How do you tell someone who you have been terrible to that you want them back? Can you say you’re sorry enough when you have hurt them so badly, they tell you they never want to talk to you again? My temper got the best of me during an argument, and I pushed my fiancee to the floor. She got up and walked out the door. I want to tell her I’m sorry, but she won’t return my calls.
