My ex (childrens dad) has bought a house in France. He went on a ferry 2 weeks ago. He's just rang and asked to see them this weekend. I've told him no. He needs to self isolate. He said he did a swab test before he boarded the Ferry AND another when he got back. Tests take 3 days for the results ( I don't believe he's taken a test). I've told him he can have them if he can show me proof he's got a clear test result since his return ( Sunday).. Otherwise he can't see them for another two weeks AIBU?
