I have a son of 6 and have been divorced for 4 years. I have my son over night sunday (recent thing), monday and tuesday ,dropping him off at school and picking him up. My ex wife works full time. Other days her mum takes and picks him up with breakfast and after school club on a thursday and friday which my ex picks him up. I’ve now asked for share care for him and will not be paying anymore maintenance. I rent a room in a house which me and my son share. She says ‘ The only time i wont pay maintenance is when he has his own bedroom’. I cant afford a house to rent. She earns £38,500 and i earn half that. What do you guys think?
