Myself and stbxh seperated in June however childcare has been rather ad-hoc over summer due to school holidays. We have both taken some leave and my parents have helped he has had them roughly 2 days a week. Although very rarely overnight but tbh I didn't mind as miss the desperately when not with me they are 8/11. We agreed when they go back to school it has to be formal and agreed 1 day a week he would have them and every other weekend. This sound fine until i push stbxh to iron out details. He is now saying he can't do same day every week and doesn't want to ask bosses to wfh same day every week. He won't even discuss what he considers a weekend or Friday-monday. Friday+Sunday etc. Just says I am trying to plan our lives away... We both work full time and I have always had to organise all child finish early to collect etc it's a week before they start school and in our parenting agreement both said this would be set out by mid August but whenever I try to engage about it get shut down.. I genuinely believe kids need set routine and to know where they stand especially 11 year old starts secondary in sept so big change and he really still just puts his needs first. Arghh sorry am I being unreasonable..??
