I was looking to get LO(20 months) a chucky costume for Halloween this year. It is my turn to have him for Halloween as ex had him last year. Last year we both went shopping for his costume together and got him a lion costume. Ex is insistent that I was the only one to decide on the costume and he had no say. Tbh I don't remember the day very well so that could be the case but ex has form for exaggerating and "remembering" situations differently to suit his cause.
My aibu is once I mentioned my costume plans to ex he immediately put his foot down and insisted I can't dress him as chucky as children should only be cute on Halloween and not creepy or scary. I pointed out if it was his Halloween he could dress him in whatever he liked and I also said his reasoning was ridiculous as its a good costume idea and there's no specific "rules" as to how toddlers should be dressed on Halloween. I wouldn't mind so much if he'd be around all day but he won't even see him in his costume chucky or otherwise.
Who's being unreasonable?
