Hello, I am due to have tea tomorrow with a male friend whose children are now living in America with his ex wife and new husband. Before they emigrated he took the mum to court to get an order that contact needed to be maintained and the judge was clear that mum and new dad must facilitate this. However since the move the teenage children 15 year old girl and 12 year old boy have had next to no contact despite friend trying on a weekly basis to send emails text and phone without any response. Ex wife says she isn’t going to make them communicate with their dad. It’s now two years without any conversation. He wants my advice on what to do next and should he carry on with these attempts even though he is finding it really hard. Any advice appreciated
