she called to tell me that we should stop as her ds was getting to hyper and then playing up at school, since then she whispers to say hello when we walk past each other so they dont hear or see each other , I have had to send her ds back to her in the morns or they both change and become a nightmare, I feel bad and its has really hurt me i told her as I felt she was blaming my son although she denied this,things have become strained aibu.
