About 6 months ago we were on our way out to dinner with good friends (who also are our neighbours). They were arguing in the back and he punched her. Lost the plot completely. Anyway, after an evening of sorting out she was safe but still wanting to be with him and some conversations about it she went home but not until she had told us the extent of the abuse. He does not know that we know the extent of everything. Dh and I decided actually that the friendship was never going to recover and we didn’t want to be friends particularly with him. We have gone on the last few months with just courteous hellos on the drive only. We have not told anyone
Fast forward to this week and our neighbour is being an arse and has clearly told their family a different reason as to why our friendship ended and we are being blanked and they are playing the victim. I am probably Abu , but I feel I want to tell people the real reason we are no longer friends 
AIBU?
