Cheating ocd

Does anyone ever wonder if they ever emotionally cheated ? Sometimes I feel like I have In the beginning of the relationship but I’m not too sure or maybe I just in denial and don’t want to admit it . I’ve told my partner about this awhile back . He didn’t know emotionally cheating was a thing and he doesn’t believe in it and told me to let it go so I guess I should let it go . I would say why I question if I emotionally cheated but that’s extra stuff to type . whenever I’m around other males I get feeling like I want them and they feel so real . I honestly don’t truly know what emotionally cheating is but I have a guess and I’m scared to look it up . I guess I’ll say why I feel the way I do . So there was this twitch streamer I had a on and off crush on . I started watching him when I was 18 and his was like 25 . And lived in a different state . It was a unrealistic crush now that a look back at it bc I wouldn’t never happened but I still had a crush on him. When me and my boyfriend first started dating . We were playing a game online and I decided to stream bc I sometimes like to stream and I was looking for that person I used to have a crush on to join the stream and say hi . I sometimes wonder did I still have a crush on him . Was I emotionally cheating . Again, I’ve told my boyfriend all about this . He felt some type of way bc he didn’t know but he didn’t think it was a big deal . But my boyfriend does have cheating ocd . But it’s the type of cheating ocd where he thinks I’m cheating. But it’s like physical type of cheat .Ike when he’s away at work that’s when his thoughts get bad . Bc he thinks I’m sleeping with someone . I never had sex with anyone ever besides him . When he talks to me about his cheating ocd it triggers mine lol. I guess I should let all this go idk.

My ocd is telling me I cheated on my partner 3 years ago but I don’t have any evidence at all. I keep thinking maybe I got my timing off because I was seeing someone a few months before him, but my ocd is saying that was at the same time. Any advice? Should I confess something that might have been three years ago with no evidence? How do I let go?

my mind keeps saying i was cheating and i just need help. a while ago me and my partner went on a break because i was unsure of my feelings. i saw this guy at lunch that was alone and i thought was cute and i thought i had feelings. me and my friends invited him over and we all became friends. i realized later i didn’t have feelings for him and i did truly have feelings for my partner. i never flirted with this guy, the only thing i ever said was i didn’t have anyone to go to hoco with meaning i wanted to go with everyone in that group- including him. that part makes me feel so gross and like i did something wrong. i can’t tell if what is true because my mind can’t remember- it mix’s up the story to think i wanted to go hang out with him at hoco with everyone. did i wanna be with him? i don’t think so because i obvi realized i didn’t have feelings but idk what’s true from the past. what if i did?? me and my partner are together again obvi and i cannot be around him without these thoughts of wanting to “confess”. i’m still friends with that dude and i no longer think he is that cute tbh and i figured out i didn’t have feelings for him. help??
