So my ex who hasn’t seen our child in 6 years told them he was coming today to take them Xmas shopping and hasn’t showed up, no contact from him what so ever and he last messaged them one week ago, this is something he use to do when he was seeing them make constant arrangements to turn up then just not show up at all. I’m not going to allow him to do that again this time round so how should I proceed with this as I’ve been told that regardless of this behaviour I should still allow him to see them again after 2 years not bothering?
