I just need to talk about intense jealousy

I can’t stop overthinking about my friend and her soon-to-be boyfriend , I feel like I’m jealous but not of HER, I’m jealous of HIM, like, I’ve known her for so much longer , me and her have always been closer, and this guy comes in and is gonna take up a bunch of her time. Idk, ik I shouldn’t feel this way. She reassured me she would never leave me and I guess I’m also scared of that. I had a breakup with our friend oldest bsf a couple months ago , I guess that might’ve done more damage than I thought. I feel like I’m losing myself , and then I thought I found myself again once me, my bsf , and the guy became friends , but as soon as I found oit she liked him and he liked her its like everything crashed:/// I hate feeling this way but idk what to do

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 just randomly had this thought when I was driving and I’m super anxious. A couple weeks back I was really jealous of my gf and her guy friends playing card games together in one of their classes and I wanted to see if she would get jealous if I was paying more attention to my friends in my class, two boys one girl. She was in the class and my teacher was explaining a card game to one of my friends who is a girl and I was trying to see what he was saying and showing her but I had to get closer to do that and in the back of my mind I think I was trying to make her jealous by being closer to another girl. I’m terrified because I would never flirt or do anything with another girl. That girl also has a boyfriend. I’m just stuck in my thoughts right now and don’t feel like moving or doing anything, I feel like throwing up. Someone please comment and help me
