About 14 months ago, I mistakenly assumed my dd (who was 7, nearly 8) knew there was no such thing as the Easter bunny. We had never really 'done' the Easter bunny. Just egg hunts and chocolate. She seemed non plussed, but then told her cousin who was upset. SIL was furious. I apologised to SIL. I spoke to dd, who told me she had believed in the Easter bunny until I told her it wasnt real. I felt terrible and apologised. Dd was upset, DH was furious with me. I felt awful, ate lots of humble pie. I got it wrong. A few weeks later we had a lovely Easter nonetheless.
Fast forward to this year, dd (now 8, nearly 9) has been crying to dh that she is upset because she now knows the Easter bunny isnt real. She actually said 'I still believe in the Easter bunny, I just know it doesnt visit this house'. DH is once again furious with me. She keeps crying and he keeps telling her it is ok and she can believe if she wants and trying to placate her by repeating how wrong mummy was. She feels very hard done by and I'm getting grumpy face and sad eyes from her.
I feel really pissed off - I have pulled out all of the stops this year to make Easter fun in lockdown. Shes going to have a lovely day tomorrow. We have been talking about the Easter Egg hunt and how exciting it all is. Despite my feelings, I have tried to be very gentle to sort things out and make her feel better - I asked her if she had a nice Easter last year. She said yes. I asked her why - who made it lovely. She said 'you and daddy'. I then said that we would do the same this year because we wanted her to have a lovely time and the only difference is that she knows it is mummy and daddy who make it special. (Even though daddy has F all to do with it). I said it was fine for her to be sad, but she should realise that she isnt going to miss out on anything because mummy has done everything she can to make things special and if she chooses to stay sad she risks missing out on the fun.
Anyway, DH is now even more furious with me. He says we should have come up with an elaborate scheme to 'reignite' her belief and that I've ruined her childhood. 
I feel really pissed off. I fucked up a year ago. I am sorry. But I do everything for my kids. I always go a little bit extra for them. I feel like it's unfair to be flogged once again for my one mistake. Dd is 8. I know I can't hold it against her. But dh could be more helpful and less judgy.
AIBU to expect to be forgiven?
