should i fight for her after the break up?

I’ve been really struggling with Relationship OCD since I got married, and 3 years later, I’m afraid I’ve lost the love of my life. Between the Relationship OCD, the Religious OCD, and the Sexuality OCD, she couldn’t handle it anymore. Now that she left, the fog of doubt has faded, and I’m realizing how much I truly loved her all along. I just don’t understand how our minds can play such sabotaging tricks on us. And why? I don’t know what to do. I hope and pray we eventually get back together, but I know I need help. I want to do whatever I can to return to a place where she can feel loved by me, the way she did before ROCD took over. Is anyone here going through something similar? Has anyone overcome ROCD? Were you able to repair your relationship? I’d really appreciate any insight or advice. Thank you.

im not diagnosed but for the past five years i've been seeing A LOT of ocd symptoms in myself. i kinda accepted that i might have it and learning about people's experiences helped me a lot. i was in a really bad place when i was 16 but at some point i got better (so i thought) I've lost one relationship and i healed from loosing it and then i fell in love again. we we're together for a year and six months. i was really happy for most of the time but unfortunately we we're both not really stable mentally and we both had some mental issues. i helped my girlfriend and i supported her the best i could. she managed to move in in my city and we started living together november. at first it still was her who had a lot of issues (probably depression and being very suicidal) i was struggling and i was really stressed but i tried my best to help. i think eventually she got better in january everything was happening all at once. i've lost my job and we had to move out to a different apartment and in the same time she gained new friends at work. earlier my ocd was showing up occasionally but since that time i think it got kinda worse. i have very low self esteem and when my girlfriend got really close with one girl in her work i started feeling uneasy. i never wanted to be a jelous and controlling girlfriend but my head was constantly telling me "she's will get bored of you bc of her new friend" "she's starting to care more about her than you" and it was unbearable. we talked about it few times and she tried to reassure me but at some point i saw she's not feeling good about my self doubt and being jelous. months passed and everything was getting worse. she become more and more distant, she stopped showing me any affection, she stopped asking me on a dates, she stopped flirting and even on my birthday i had to please her to stop texting someone and focus on a movie we were watching. and now two days ago she broke up with me. few days earlier we had a serious talk and she told me she doesn't feel like doing anything romantic with me anymore and when i asked why she told me she thinks she got tired of me. i asked her what about me makes her tired and she told me "it's because you can't do and cope with anything" or smth like that (its hard to translate it to English). and i understand that it could be tiring bc i was doing bad mentally and i asked for reassurance a lot even tho i knew it's my compulsion and even tho i told her i will try not to. i am also a very anxious person and i was really stressed aboud my new job and money and a lot of things and all of it made her tired. i feel so guilty that i couldn't try harder. i feel so guilty for not noticing I'm actually loosing her earlier. or maybe i actually was noticing it by being scared when she started to be mkre excited to spend time with her friend rather than me? i don't know i just feel so bad bc i still love her and i don't know if I can't stop bit i already asked her few times if she's sure that this is what she wants and i told her i will try harder and i booked a visit with a psychiatrist but she told me she's too tired to try. im scared she's also struggling mentally. i don't really know what i even want to hear from you guys i just really want to disappear bc i can't stop blaming myself for loosing my soulmate and the best person in the entire world, the most beautiful, funny and sweet person. she doesn't need me anymore. she doesn't want me and it hurts ass hell. and the fact that it might be all my fault hurt even more

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?
