My ex is stopping my children from spending the weekend with me because we fell out over something not related to the kids. I've looked after them all their lives and now he's making up so many lies about me. He really believes his own lies. He's trying to claim money from me for anything he can think of. But he never asked for any money before and never paid child maintenance or anything. But the judge at court said I can see them every weekend until the next court hearing. Can I call the non emergency police? Anything I can do?
