Idk whether to ask my ex gf (dumped me last week)to not tell anyone about the ocd because apart of me thinks I'm doing it to just talk to her again

Told my close friend about how I think I have harm ocd and showed a video describing her experience with it so I wouldn’t have to share mine. Told him how when I see the number 22 I get paranoid that I’ll harm someone, and he gave me advice to go to a psychiatrist then left me on read after we were having a conversation prior. I’m so scared to open up to people about it and now I don’t think I will again.

Hi, I'm 17,about to be 18. I've been struggling with these thoughts for the past 8 months. I was wondering if someone experienced ever the same because I feel im "different". BACKGROUND: (I'm not diagnosed with Ocd but seeing a local counselor) About 9 months ago I cheated on my boyfriend with this guy S (who blackmailed, manipulated and molested me). Since then when I realized that what i did was very WRONG and so I started ruminating picking apart every single interaction and telling my boyfriend, i tried to remember every single detail because otherwise I felt like i was being a fraud and hiding things to save myself, i had many crisis about it because I had also what i think was false memory ocd. My boyfriend forgave me idk how tbh I still wonder. CURRENT STRUGGLE: Months ago I was sure I didn't wanna S in any way and i was sure even when everything happened. For the past 2 months tho I've been having thoughts like " Do I love S?" "I love S" "S is hot" "Would S find me hot?" "What if I want S?" " What if I don't love my boyfriend enough?" "What if I secretly want S?" "What if I see my boyfriend as a friend only?Do I?" And I tried testing my reaction to intimate scenarios with S, I'm scared I like it i dont really wanna love S or have any secret attraction, I wish I didn't have any of this and I want to be sure of my feelings for my boyfriend because I know I wanna be with him and I see a future with him like he brings me comfort. But a part of me keeps trying to convince me otherwise. Sometimes I think I'd rather die than have these thoughts. Im so scared of not being able to control my feelings, im scared I can't resist S and its giving me anxiety and making me cry. Sometimes when i think of those sexual scenarios with S or I get those thoughts my mind tells me to smile because i like it because I find it funny. It makes me doubt myself all over again. Like I'm always like I need to test if I'd feel aroused to intimate scenarios with S, lately im trying to fight this urge to test and test but my mind is like "just do it this once so you can be sure. I can never watch anything romantic or sexual or whatever because my mind would be like "you and S" or sometimes I'm just enjoying time with my bf and im like " yes we can just have a sneaky cheating thing thats ok" and it makes me want to figure it out to find an answer a solution because idk it just does like I need to find the meaning of it if it means the truth and all. Im worried im just an awful person and these thoughts just ruin my quality of life . Today i had a crisis where i ended up doinf swlf harm, I'm so scared of finding someone that's not my boyfriend desirable or sexual appealing or whatever it is, I also have bodily reactions when I try to imagine and test my reaction to scenarios. Now i keep groing everytime and I dont know why but i have this sensation and I dont want to havebit especially when its something S related. Does someone experience the same thoughts? Am I alone in this? Is this ROCD? What should i do?

When I talk about how terrible I used to be to my girlfriend it makes me feel like I’m gonna do it again which I don’t wanna do and it scares me and then I get intrusive thoughts and feelings about it doing it but I don’t want to, weird I know.
