So my ex hasn't been in contact with me or ds or dd since 30 Aug. I've tried ringing and texting him. The messages are delivered but remain unread. Dd turned 21 last week. Nothing from him no text or phone call. He lives in Ireland and ds is going over on sat - he is staying with my parents and wanted to meet his dad but ex won't answer his calls or texts. I dunno what else I can do. Could I ask the police to do a wellness check? I don't have any of his friends or family's phone numbers any more. Am actually getting worried. He has a habit of ignoring me but he usually responds to the kids .
