Ex has been with his gf 6 years or thereabouts and lives with her. They have 7 kids between them. My (our) dc are 11 and 9. DC have told me that on about 4 occasions in the past year or 2 their dad and gf have been splitting up. They've been told to pack their things as they are leaving. Then it all calms down again and normal service resumes but it's leaving the kids really anxious that if they split they'll have nowhere to go to see their dad and won't see the other kids again. His relationship is his business and nothing to do with me but how can I support the kids? I don't like how they are privy to lots of arguments and threats to split up. I'm NC with their dad due to DV and are in the middle of an acrimonious divorce.
