Thank you AndrewP and peacetoday. My kids have been a great support to me and have also been very hurt by their father's lack of interest in them ( his refusal to do anything to save our M) and the two younger ones did confront H after BD when he talked rubbish and tried to reason with him. As a result H distanced himself a lot from them and only asks to see the oldest son occasionally. So they are very hurt and angry but do understand that he is having a MLC and is not their old dad. All of them point blank refuse to have any conversation about GF and have let him know clearly. I think it makes it very difficult for H to have a normal conversation with S22 and S26 (D20 has NC with H at the moment) as it seems his whole life now involves GF... I don't know how to advise them on how to deal with the whole situation...they are very lost as well and I really want to help them but I think they worry about me too much!
