My brother ended things with his partner a year ago when my niece was 1. He took a job in London, several hours from my niece as he had no option to secure work. He comes back every weekend he can to see her. He’s currently paying more than cms would dictate and gives ex 900 a month, cms calculates it at 750. Last her knew she earned the same as him and after tax, with his 900, she has around 4,400 a month. She is now putting my brother under pressure to give her 30 pounds a week for a two hour babysitter on a Saturday so she can ‘keep on top of things as he’s a deadbeat.’ My brother can’t get up from London until late Saturday afternoon due to his work, so she is saying she is solo parenting all the time and needs a break to catch up. I get this but also see the huge financial strain my brother is under and she is often quite rude to him. AIBU in thinking she should be told enough is enough now? I was a single parent a long time ago so I KNOW it is hard but this seems to be taking the piss out of my brother who is trying his best. I am overseas as are our parents so can’t provide practical help.
