I am a single Mum to 3 children aged 12, 10 and 5. They live with me full time (no court order in place and no real routine with when they see their Dad which is causing all manor of problems but that's a separate issue).
They do see their Dad most weekends and sometimes in the week but the kids often don't want to. We still own the house jointly so legally he can come and go as he wants to. Recently he has arranged to take them out but the kids do not want to go. The oldest has a terrible relationship with his Dad and wants very little to do with him. The 10 year old is very clingy and tearful and just wants to stay with me and the 5 year old is happyl to go some of the time but other times just sobs.
Would you force the kids to go or just make them available and if they won't go don't make an issue of it? Their Dad does often see them at the house but they don't want to go out with him. I think they feel more secure at home. He gets very angry with me when the children don't want to go with him.
