i am the exact same way, but I've learned to tone it down. when he and i first started dating, it hit super hard - i confessed to so many things, and his responses were always the same: "i don't love you any less, you're a good person," things like that. but whenever a new obsession would come up, my brain would tell me "this time is different, he's gonna hate you, you have to tell him so he knows what a monster you are". but of course it was never any different. you do not have to tell your significant other every single obsession. that in and of itself will become an obsession.
