Long time lurker, first time post. For the first time in 2 years my Dd 11, had arranged to stay over at her dad's for the weekend so she could spend more time with half siblings and him, she normally goes one day every other weekend (her choice, as doesn't get on with step mum) she was very excited as she was dropped off this morning. This afternoon she messaged me to say she was unsure about staying over, so I called her to talk ( she refuses to talk to her dad about it as she's scared), to reassure her, I asked to speak to her dad to let him know what was going on, all very polite, explained she was worried as hadn't stayed over there for a while but she could come home if she wanted. Left it up to her, later this evening she came home, floods of tears as she came in as she had heard her dad and step mum bad mouthing me after the call and dad saying that I swore at him. This did not happen, both me and Dp were shocked as he was with me when I was on the phone to daughter's dad. Daughter's dad has a history of lying, he cheated on me with his now current wife and to justify this he told mutual friends and his family I was violent to him. Again this was not true and he is now estranged from his family and many mutual friends because they saw through the lies. So I suppose my aibu is do I tell him she wanted to come home because she heard him bad mouthing me again or not. She has also said she doesn't want to go around again.
