Struggling with relationship OCD (cheating)

Hi everyone! I have been having a rough time. So my boyfriend talks to his ex still as friends and I’ve been struggling with it lately and I can’t tell if it’s OCD or not but it does feel so distressing. She wasn’t texting him for about 2-3 months as she got into a relationship with this guy and they broke up. She had messaged him saying that she has no one else to talk to and needed to vent to someone. At first I felt okay, but my intrusive thoughts took over and it seemed like she was trying to get with him after the fact. It’s probably just my intrusive thoughts talking but he looks on Discord (the app where the message) constantly now and my intrusive thoughts convince me that he’s still in love with her. Then yesterday I saw one of his BeReals (a little photo app that shows a photo of the day) and I saw that he was watching one of her streams as she is a streamer. I struggled to talk about it because it made my worst thought feel like it came true where he is still in love with her. When we talked he gets a lil mad that I don’t tell him right away like straight up what I’m feeling but it’s hard to process because my thoughts flood in of all the worst things and I don’t want to come off as toxic at all and I know relationships are built on trust and I want to trust because this is literally the only thing that makes me nervous about him. It also doesn’t help that I’ve been cheated on before so I’m trying to protect myself but I’m lost. I get so depressed and so anxious because I feel like I have to grieve the relationship and it’s just so dramatic. I’ve never loved anyone like this before and I don’t wanna lose him by bringing this stuff up constantly when something occurs with his ex. I don’t know why I get triggered so easily and I just wanna heal from it and be the good girlfriend I’m supposed to be 😭

I have this deep fear I’ll accidentally cheat on my long term partner. This fear was initially triggered a couple years ago after being at a bar with my friends where I enjoyed the attention of being flirted with by a stranger. Because of my enjoyment of receiving verbal attention, I began spiraling about what if I accidentally cheat. Since then I have made multiple confessions to my partner to seek reassurance, replayed events over and over in my head, spent hours googling/looking at reddit threads, and now I dread “bar like” situations where I know my partner won’t be around. Today I was triggered and have wasted about 4-5 hours of my day ruminating. Does anyone else with relationship ocd struggle with this fear and have any tips?

Despite the fact that I have never once acted flirtatiously with someone else over the course of my 3-year relationship, never talked to anyone inappropriately, never touched or interacted with anyone inappropriately, I have been battling constant ROCD obsessions centered around cheating ever since my partner and I got together. I am constantly worried about whether certain things are cheating: daydreaming about another person (already told my partner about this and he said it was okay and that he does it too), talking in a group chat with someone, sitting next to someone, speaking to them in person. I question my intentions. I worry that I cheated by wearing my hair a certain way in an attempt to look more attractive or by jokingly poking someone with a fake sword (despite doing it to other people too), looking through someone’s social media, etc. I have confessed so many ridiculous things to my partner and he’s always told me that none of them are cheating. I feel so guilty for being attracted to someone else, despite the fact that my partner said it was fine and normal. I have made a very very conscious effort to limit my interactions with this person. I never ever ever ever message them privately, I make an obsessive effort to NOT reply to their messages in a group server (constantly keeping track of the ratio of my replies to their messages compared to other people’s), to ignore them when I see them in person and hardly ever speak to them or initiate conversation with them. Yet I still feel like a disgusting dirty cheater who is hiding a big secret.
