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 😭

for me it’s getting to the point where i don’t feel in love with my boyfriend anymore. i’m trying to keep myself from compulsing since my compulsions are all mental. it’s like the thoughts consume my mind every second of every day and i can’t catch a break. it’s like i want to be with him so bad but my brain won’t allow me. any advice?
