I split with my ex of 12 years in February but we are still living together as he is delaying the financial settlement and I’m a stay at home parent with no income so I can’t move out. We have a 20 month old and 5yr old and my ex wants the children 50/50 even though up until a few months ago, it was 80/20 all the time and he travelled abroad extensively with work as well. I agreed to trial a schedule where he has the children three days per week. He unilaterally decided on the days that both children are at school and nursery and one weekend day (which he often asks for help on) and will still expect me to look after the kids if he’s got meetings on those days. Yesterday he told me that he will be changing the days he has them with one of the days being when our 20 month old isn’t in nursery and I usually have him and take him to classes. My ex said that he wouldn’t be able to take him as he needs to work. I’ve been keeping a diary of when he goes into the office - 5 times in the last 4 months and very often he is still in bed at 11am or is sat watching tv. He told me that he has hired a nanny to look after our son and pick our daughter up after school. I was absolutely furious that he didn’t think he had to discuss the change of days and nanny with me. If he had done, I’d have been more than happy for our son to potentially do extra day at nursery. He can’t understand why I’m so upset. Am I overreacting?
