did i cheat?? ROCD

Need some advice please! Went out with friends the other night - both of them are single and I have been in my wonderful relationship for over a year now. Anyways, my friend met a guy and he offered to buy us some drinks. Both my friends went to the bathroom and I decided to stay behind and watch all our drinks (safety reasons obvi since we don’t know this man). A man was talking to the guy we were with and I was relieved I didn’t need to make conversation with him when all of a sudden the guy we were with goes to the other man “hey my girlfriend and I here are trying to have a nice date night together and enjoy each other’s company, would you mind?” And I was completely thrown off. I felt so uncomfortable and had to go along with it, and the other man was like “what do you like about your bf?” And I was like Um he’s a cool guy I guess and it becomes this big false story. The man leaves and this guy then asks me “have you ever had that happen to you before? Have a guy pretend to be your boyfriend?” And I immediately was like “no I haven’t. Normally MY boyfriend is with me lol.” Shut it down right away. Then the guy started asking about my friends again. Anyways long story short, my OCD spiked after this. My mind has been replaying the event over and over to check and make sure I didn’t flirt. My mind is also saying “did I like he was trying to flirt with me? Did I want to flirt back? Did I flirt back? Maybe I flirted?” I had a quick thought it could be a cute story at first for how someone would meet for the first time, not me obviously but someone else, but then the more I thought about it the more I just thought this guy was plain rude. I told my boyfriend the entire story that same night and he just said the guys a weirdo (which he was) and he’s sure I didn’t do anything wrong. But I still feel so guilty for some reason? Any advice? Also want to say I know I would never ever do anything to jeopardize my relationship with my boyfriend, nor do I even have any desire for other mens attention. I was just super uncomfortable I was even put in that situation.

I can’t stop thinking about a time the thoight of cheating crossed my mind at a party and I was like “no it’s against my morals” and then started ruminating about it for hours thinking that maybe I should break up with my partner if I’m attracted to someone else I was cold and didn’t talk to the person the whole time ofc (I don’t really know them I just saw them that one time and they were hitting on me - which I rudely rejected and said I had a bf) I feel terrible. I feel like a cheater. I’ve been told I’m not but why do I still feel like I am? I feel like I betrayed my partner and I feel terrible and disgusting to the point I’ve been cutting myself.

so back in july i made a mistake of going behind my partner’s back and hanging out with an old guy friend (who i had a romantic past with) and while i was hanging out with him i had a great time but man my thoughts were going crazy. i found him attractive, funny, etc. i’ve known him for years and everytime we would talk i felt there was some type of tension. like romantic or something. well i felt it again when we hung out and immediately regretted it because i know i love my boyfriend a lot and i felt like a horrible person for doing something like that. i couldn’t hide it from him any longer than i did (not even 3 days) so i told him and he got really upset. at the time i didn’t know what i want, either my boyfriend or that friend. i decided to stay with my boyfriend and ever since i’ve been getting crazy intrusive thoughts about my old friend (i blocked him so i don’t have contact with him). a few months later (now) i know that i want and love my boyfriend, i don’t want to be with anyone else. but i’ve been getting so many intrusive thoughts about that guy and seeing certain posts just remind me of him even when i don’t want them to. then my brain starts to spiral - ‘what if you actually want to be with him instead and you’re just in denial right now’ or something like ‘you dont love your boyfriend, if you did you wouldnt be having these thoughts’ and i’m just so..drained. i’m so tired of thinking about this guy, i seriously don’t want to think about him. i just want to be happy with my boyfriend. i keep telling myself i know what i want, because i do. i want to be with my bf and i want to be happy with him…i love him so much. but my brain just tries to tell me otherwise. i know i messed up and i’m paying the price for it. maybe i do deserve this. i just wish i could erase everything, my past, etc. and just move on. my boyfriend doesn’t hold what i did against me but he’s well aware of what happened and i know how it made him feel. i would do anything to take it back because he doesn’t deserve that, he never did. and i seriously want to be better for him. but these constant thoughts i get are always getting in the way and almost making me feel hopeless. i haven’t told my bf about these thoughts because i’m worried he would take it the wrong way. i really don’t think i should tell him because i know for a fact it would send us both down a spiral and i don’t want that. but, ocd will always try to get what it wants. anyone else going through something similar? some common humanity would probably ease my mind a bit. (in a non-compulsive way. or maybe this is a compulsion. idk.)
