I have two young kids with my ex, he can only see the kids with a responsible adult because he is often drunk, and his drinking makes his mental health issues worse. The responsible adult was me for a bit but I couldn’t take it any more so his parents were doing it. Over Christmas he had a massive drunken row with his parents (no kids involved) and then turned up drunk for the agreed access a few days later. I don’t feel I can use them for access again, but need visits to be supervised. Local contact centre is closed for Covid. What else can I do? Don’t want to cut off all contact but need to protect the kids.
