My son has a best friend who he has known since he was 6 years old. Now that they are both at secondary school I had an arrangement with the mum of his best friend and another friend (who has a son who is close friends with my son as well) where on Mondays, Tuesdays and Fridays Mum B would take the boys to school and bring them back and on Wednesdays and Thursdays I would take the boys to school and Mum A (sons best friends mum) would pick them up. Mum A also has 2 boys in my daughters school of which 1 is in the same class as my daughter. Last Saturday Mum A asked me if the boys could walk to school and come back home together. I said no as there are no buses that run there and back and also it would take them 30 mins there to walk and 30 mins to walk back. I also told her that I would be taking my son there myself and back. She told me that was fine. Then on Tuesday morning Mum B text me to say if I was taking my son to Mums As house as on Monday morning she waited for me to turn up and I made her late. I text her back to tell her that I did actually tell Mum A that I would be taking my son there myself. She then text me back after 15mins to tell me that Mum A told her that I never told her that I would be taking my son to school and picking him up and if I wanted to continue for Mum A to take him to school I had better let Mum A know or Mum A wouldn't be doing it for me no more. I am now really left upset because Mum A and Mum B are ignoring me when they see me at the school. I did try to say hello to them both but they both just ignored me. I invited Mum As 2 younger boys to my daughters birthday next weekend (before this had happened) and she said she would bring them. But should I confirm with her if she is bringing them or just wait and see? My husband thinks I shouldn't bother asking her as she probably wont see them but her son who is in my daughters class has said to her today that they will be coming.
