Asking on behalf of my friend, she's got three dcs 18, 17 and 15. She's been divorced for 10 years, she's getting married soon and doesn't really want to tell her ex. She doesn't have a good relationship with him, and she feels like her kids are nearly young adults, they see their father when they want so there's no need to tell him. She knows her kids will tell him, but she doesn't want to speak to him. What do you think?
