i would love tips on how to reduce ruminating pls!

this is a weird post to make but i’ve been having a really hard time not ruminating :/ my mind is constantly asking me whether or not it’s appropriate to like certain people and then i dwell on it and look back just can’t remember how certain things played out. i would love to just ignore this and go about my day, but what if a crush started problematically? that brings me to my current obsession; i watched superman 2025 back in july when it was in theaters and loved it. i even got so invested that i wanted to start reading the comics, make a fan account, and watch smallville. the thing that i’m worried about is that i only started crushing on superman after watching smallville. i genuinely can’t remember if i was crushing on him after watching the movie or the show. the reason why this concerns me is because although the actor for clark kent in smallville is a 24 year old man he’s still only playing the role of a high schooler since this series focuses on his time in smallville. it would be really weird if i started having a crush on the 2025 version superman after watching a “teen” version of him. i don’t even like the teen version of him, i think the adult actor is very attractive but the fact that he’s playing a kid obviously makes him unappealing to me. i would like to keep liking superman 2025 but i feel scared that this crush started out strangely… could it be that i just gained a stronger appreciation for superman after engaging with more superman related media? also how do i stop ruminating about such things when it always feels like life or death?
