Struggling with OCD and Guilt

I think I’m a bad person! So I’ve struggled with this OCD theme for almost a year now maybe even longer on and off. My fear is that I cheated. I feel so much guilt and shame. Over a few events. The first one was a male guy friend who I’ve know for years prior to my bf. We chatted a lot about school and I sent him a video of my bf and I . But I didn’t inform my boyfriend I believe out of fear because my ex when I was 16 controlled and isolated me. And I live out of fear of peoples reactions. I obsess about that I sent him tik tok videos and pictures of myself and talked about my makeup and make jokes as well. Another thing I feel bad about is virtual games I used to play like Roblox lol. I would have random convos and troll people. I’m freaking out just typing this.
