How do I stop over analyzing everything?

I know he’s not cheating on me. He’d never do that and, as hard as I try to tell myself “he’s proven already that he’s not” and show myself all the signs of commitment and dedication, I still have that fear. It’s eating at me and ruining my relationship. How do you guys get over this? If my brain were true he’d have been cheating on me for months in ways that aren’t even possible. It doesn’t make sense if I think about it logically but it seems like when I do, I create in my head more ways for it to be logically true. What is your advice? How can I stop self sabotaging?

How do you guys get past the anxiety? I feel like my thoughts are the only thing that control my mind. So often I feel like I should just leave my partner even tho I love them so much because I just feel like these thoughts are too much. I over analyze everything. I feel so stuck and defeated. I just want to be normal. I feel so toxic for the thoughts that I have

Today I've let myself go down a huge rabbit hole regarding this phrase and it's stressing me out. Sometimes, yes, it is that deep. But other times, it really isn't. I keep finding myself torn between these two ideals. I've been seeing all these videos regarding the rise of anti-intellectualism and the anti-woke mob, all that. These videos make me extremely worried about cancel culture and moral guilt, and they had me rethinking every morally wrong, gross, questionable thing or thought I ever had. I saw many comments saying that yes everything is that deep and it feels like my mind is on constant security and asking myself "what would the internet think about the things I've thought of or may have done?" On one hand, I feel like if I say "it's not that deep", I feel like a hypocrite or a bad person or an idiot. But on the other hand if I say "it is that deep", my OCD begins to spiral and analyze everything about myself. It's not healthy to overanalyze everything but it's also not healthy to ignore bad things. It's very stressful Does anyone relate to this?
