My ex has not been involved in our children’s lives for a few years now, he suffers from significant mental health problems and says this is the reason, every time he sees them it becomes too much for him and he backs off and disappears again, this could be anywhere from a few month to years, he hasn’t seen them properly now in 4 years apart from a few time’s where he’s popped up again. Seen them briefly then faded away again, he’s gone for well over a year at time’s when he hadn’t seen them at all, as the children are getting older they have started to realise what he is like and don’t want anything to do with him anymore. He thinks this is my fault when in reality it isn’t, I never speak about him to them and I don’t bad mouth him, he tells me I should tell them he is ill and that’s the reason he doesn’t see them, he also thinks I should be understanding and that other people would be, which I’m struggling with as I have my own problems but I don’t just abandon my kids for years. So I guess basically I am asking if there is ever a good reason not to see your children? And if I should tell them it’s because he is ill?
