Didn't want to post in aibu but my ex is being a dick.
DD has a dance showcase on her contact weekend with him. I asked him kindly to bring her and gave him details and ticket information to buy himself one.
He's now royally kicked off because I've been asked to parent help as I have a full children's and adults DBS. Essentially is telling me I'm not allowed to be back stage with DD as it's his contact time.
I am one of very few parents of kids in the class who has a full dbs and was approached by the class teacher to help.
I need to tread carefully however as DDs dad is a monumentally dick and has purposely prevented her from going to parties, events and shows. She'd be heartbroken to miss out on the show after months of rehearsals.
Should I decline parent helping for DDs sake but also know her dad will know he can just bully me and I'll back down every time.
He is high conflict and I left him because he was abusive.
