I need help, what if i want to cheat?

My boyfriend and I have been together for almost a year coming this May. I have never had feelings for someone like this and I genuinely see myself living the rest of my life with him. Talking to him comes effortlessly. He sees me for all that I am and works with me. My family has already begun developing a connection with him as well as I have with his family. I’ve never felt so at home until meeting him. Lately my ROCD symptoms have been playing on the narrative of him either finding a new girl that interests him and is somehow “better” than me OR me ruining our relationship because of potential cheating I have absolutely no actual interest in cheating because I know he’s my person and so am his. I know I’m going to marry him and I know that I want him to be the father of my kids. I want to see him grow and I want to build a foundation of unconditional love with him. So why do I shame myself? There’s this shop that him and I go to quite frequently, and the last time we went an employer that we typically see every-time we come began talking to me personally. We were all just talking about movies but my boyfriend mentioned that he felt like he was flirting with me. I begun feeling bad like I was doing something wrong. My mind started telling me that I liked having him “flirt” with me and that it made me feel desirable and confident in knowing that I was still considered attractive. I’m scared because now everytime we go the employee seems to be staring at me and when I went today he actually gave me something for free which led to me thinking I was playing into the flirting narrative and that this would lead to something worse (Though I still have no interest in doing so, just anxiety about that happening is the best way to put it) Has anyone else experienced something similar? Is there any advice that can be given? I don’t think anything’s going to happen, but what If I do like knowing someone likes me even if it’s not reciprocated? Does that make me a cheater? Or is that the product of unresolved self worth issues?

i saw someone triggers me A LOT. Looking at beautiful looking people has always triggered me. I feel horrible and i feel like i cheated. Finding someone handsome in a relationship is not normal to me i don't know i feel horrible and i feel like i cheated. I didn't feel attracted, but i feel like i cheated so much i hate myself i hate my eyes thats wht i don't look at anyone. I hate looking at people and finding someone beautiful. I feel so guilty. Please help me im begging i need to talk someone. I had this in past, i hate that when that happens. I DON'T want to find anyone good looking. I DON'T want to anyone come to my mind except my partner. I won't act on that thoughts but i feel like im betraying my partner anyway
