ok so yesterday my ex dropped the kids home and dropped it on me that he had talked to the kids and they all want to live with him for a week and then with me for a week and so on, ive never stopped them seeing their dad and i would never he is a good dad im just a bit worried about this i dont want to disrupt my kids its such a change in routine for them but its what they want and id feel awful saying no because they need their dad as much as they need me. maybe im being selfish and dont want to share them i dont know but my first worry is how will it affect my kids does anyone else share their kids like this, am i making a mistake by letting them try it out?
