Split from my ex 8 months ago. We had a childcare arrangement in place where he takes DS two days a week and I pay for a days nursery so I can still work but I have had to reduce my hours. Currently he does no weekends and does not pay child support yet he does bank shifts with work frequently. For note I live in England as a lone parent with no family living here. He lives with his mum, brother and stepdad and has lots of family close by. I asked him if we could change our childcare rota around so I could work the odd weekend (nhs so I get enhancement pay) and to be honest I think it's only fair. He will never take him if I was offered to go to a hen do once in a blue moon or any event. I also buy all his clothes and send them to his dad's, pay for nursery so he doesn't have to take him the third day and even bought the travel cot, mattress, sleeping bag etc for his dad's house. The response I get is that he is his dad not my childcare so will only see him on his terms? Which I think if I didn't have a schedule in place sadly would be once a month as he doesn't seem to care. There has been issues in the past with domestic violence and controlling behaviour so not really sure what to do in this situation. Any help would be appreciated
