Ex is a bully, used to bullying people to get his own way. We had a child agreement in place, no legal bearing and no court order. But a fixed agreement in writing. Ex lives abroad so I have DC mostly in term time and ex in the holidays. From the start of lockdown ex has been in UK living near to us. He suggested dividing child care 50/50 due to coronavirus which I agreed. Obviously, coronavirus has lasted a lot longer than expected and ex has been seeing DC much more than on previous schedule. I assumed because of this we would also divide summer holidays equally. No. Ex has stated that he should still get the majority of summer holidays (5 weeks) with DC. He is saying we have a (previously) agreed schedule that we need to stick to! I am saying we haven't stuck to it because we've been seeing DC equally for the past 3 months. We could go round in circles for ever. What is fair here?
