Anyone break up because of ROCD?

Hey, my girlfriend recently broke up with me and immediately got with a guy she had told me not to worry about. For her side of things, she hadn’t admitted to herself that she had feelings for him but then started thinking she was polyamorous since she says she has feelings for both of us. Since I’m not poly, she decided it wasn’t fair to me if she had feelings for this guy. But it really hurts since 1. I have ROCD and was terrified this would happen 2. They were flirting in front of me the other day after she had assured me she didn’t have feelings for him and 3. They had agreed to date before we had broken up, even if they only made it official afterwards. I can’t help wondering if her feelings for me were all a lie until something better came along, and since this was my first relationship it feels like I’m unlovable. Even if she says she broke up with me because she’s questioning her identity, it still feels like I’m just a side character in the love story of someone else more important and worthwhile. My OCD has really latched onto it all because it feels proven right. Any advice?

I need some opinions. I have had ROCD (I think) for about 1.5 years now and I have had crazy thoughts since then. Tonight I feel as if, if we were to break up I wld be happy and not care at all anymore

i have always been a pretty doubtful and overthinking person all my life, but i have never had bad ocd until something happened in my current relationship i met my boyfriend senior year of highschool, we started off as friends first but then would text all night and found out we have a lot in common, he still lived at his parents house at the time, i'd go over to his or he'd come over to mine sometimes, your typical teen romance story, my rocd didn't start acting up till we started getting serious fast forward to when i started working at my old job and met this guy who pretty much love bombed me, i didn't know it at the time, and so i lost myself during that time trying to balance everyone's feelings, i ended up hurting my current boyfriend really badly and ever since ive had raging rocd, every second of every day i cut this guy off and me and my boyfriend are still together, working it out, and then two christmases ago he gets kicked out of his house, and starts living with me and my family, a huge change i wasn't ready for but it happened my family loves my boyfriend, everyone i've ever introduced him to also does, he truly is an angel, he's so sweet and good to me, i've met all his friends and he's met mine, i could picture a life with him, but currently my rocd is too much to bear, id be better alone but im so deep in this now it's crippling, i can't hangout with my friends without rocd, cant wake up without rocd, cant think of anything without rocd, i cant eat or sleep, life feels like it's no longer real, the relief of breaking up with my boyfriend would free me, but i cant bring myself to, ive tried multiple times, i might just be a coward because i dont want to hurt him again, i dont want to lose him, but ive lost myself, this rocd is driving me insane lets say I break up with my boyfriend, he already got kicked out of his old house and I do not want him to have to feel like he's got to be kicked out again, this is his home now and I just couldn't do that to him, my family would lose someone they see as a son, and I would have to watch him move his stuff which would make me so sad because I care so much for him, I would even move out just so he doesn't have to the thing is I really can't put myself through this anymore, I have to put myself first or this will kill me, idk what to do maybe i could talk to him about how bad my ocd is, tell him that i really have tried to push through but i need a break, maybe we could be friends and work it out? i hope so
