My (22F) partner (32F) thinks I’m a pedophile for watching movies with children/teens in then

I (22F) have finished watching The Last of Us season 1 and, liking the acting of Bella Ramsey and seeing another of her movies “Catherine called Birdy” on tiktok, decided to watch that film. After telling my partner (32F) of 3 years that I was watching this I was promptly told it was weird to watch so many things with kids in them or adults acting as kids. (I have watched stranger things and shows like that in the past and never thought anything about the main characters) I must add a critical detail that may sway your answers: I made a mistake when I was young by on-line “dating” someone who was a couple years younger. Long story short it was on an app called Amino which is an app for fans of any show or movie to join and talk with people who liked the same thing. I can’t specify age but they were younger and I was young but almost an adult but I know (now) that should’ve been enough for me to not even really try to be friends but, in this small group where there were people older than me, I really saw no issue with being friends with this person in the first place and the group aged from 13 1/2 to 26. We both were in a small group chat of people and they all knew we were “dating” but no one there had said to me it was wrong or weird so I hadn’t seen it that way especially as we never acted like anything more than best friends. I’m a pretty naive person and at the time didn’t think anything was wrong with that as we didn’t go anywhere serious, romantic or sexual. I know now that whole situation was wrong as I turned 18 while they were obviously still under and had “dated” only for a week or so after I turned 18. I know I can’t do anything to change the past but recognise it was wrong. I also don’t see myself as a pedophile as I never sexualised or perused them in reality; though I know technically and legally it probably does make me a pedophile. I would just like a few more opinions from other people but I will no longer watch child focussed actors in movies or shows as that’s really not my motive for watching things and it sucks someone else could see me/my intentions that way. Be honest
