OP, I completely understand how you feel. Not exactly the same scenario but…..
Videos weren’t a thing when I got married and the agreement with the Vicar was no cameras past the church door, which my husband and I were in agreement with. We have a lovely professional photo of us leaving the church, taken in the porch, but there were none in the church. The Vicar himself audio recorded the service and we listened to that a few times (mainly for the music).
However, one of my father’s friends took it upon himself to ‘anonymously’ pay the bill for the church, organist and choir. I’m sure it was meant kindly but it still, after 48 years, annoys me. I/we would have preferred a ‘proper’ present from him and his wife, and to have paid for our wedding ourselves. I don’t know if he didn’t realise it would be obvious to us it was him by the fact that he knew the Vicar and he and his wife didn’t give us a regular present.
We still have presents we use which we treasure and remember the givers kindly. This non-gift and taking some of our ownership of our day away still niggles. In theory we couldn’t even thank him.
I can’t advise you but I wanted to say not to feel the people saying you are over dramatic, should put it behind you, etc. etc. are right. Only you know your feelings and maybe you will calm them in time, maybe not.
In the meantime, have a wonderful marriage and remember that’s the important thing, the wedding is ‘just’ a day, albeit an important one, but the main thing is the marriage.
