My partner and I are moving with our 3 children (one of whom is the child of my ex husband). The distance is approximately 30 minutes from where we currently live. My ex is demanding that we meet half way whereas currently he or his partner collect the child from school/grandparents house as he lives close by. He has a partner and no children with her and I have children aged 9 to 2. Am I obliged to follow his demands?
