I want advice

My partner broke up with my about 10 months ago. It came out of nowhere, and I got no explanation before they ghosted me and blocked me on all forms of contact. I have been horribly struggling since then with this obsessive need for closure. For a while I continued to try to reach out to them, on my own accord or through other people, but it just kept ending with more blocking. For months, I was going through the relationship and the breakup in my head over and over, picking it apart to try and figure out what went wrong, but without a conversation with my ex, I couldn't get anywhere. I am definitely doing much better now. the compulsions to reach out to her and the spiral obsession with figuring out what went wrong have both lessened. but they are still present, especially when I sleep. I really just want to be rid of the whole situation, but i want to do it in a healthy way without locking up my feelings. i really am at such a loss though. i still want answers and i still miss my ex in a lot of ways, but at the same time, the though of running into them scares the shit out of me. ive heard some horrible things about them since then, and how they have been spreading rumors about me behind my back. the situation cant seem to get any worse and it just keep happening. and it makes my ocd triggers so much worse too. idk, i will take literally any responses and any helpful advice.

My ex best friend started dating my ex boyfriend. And me and the boy are in the same church so this is awkward. My heart is broken, not because he’s with someone else but the fact that it’s with her. I look back at every moment the three of us spent together and just wondering if they liked each other when me and him were together. I’ve lost all self respect, I keep stalking them on social media and I’m so mad at myself because I know that I’m letting them hurt me more but I can’t help it. I also still have my ex bsf location and I checked it today and saw that she was at my ex bf’s little brother’s baseball game, this hurt because me and him used to do that together, also me and his family are still close because of church so I have a soft spot in my heart for his little brother. I just feel like my whole world is upside down, I’m so confused. I’m trying so hard not to resent them, I try and remind myself that they are still God’s children. But I still find myself full of bitterness. I’ve been processing everything for about a month and I have tried tons of things to heal: put all of the items he gave me in a box, go to a rage room, visit the temple, journal, pray. Each of these things have helped a ton, but I still have a lot of pain. I know that this is all part of God’s plan but it’s still painful, I just need to remember that this pain is temporary and will help me grow as a person. I just wanted to share this and maybe get some advice on how to heal from a broken heart. I know this isn’t really OCD related but I just really needed to share this.

Does anyone have advice for dealing with a breakup. This hurts so bad and my brain is torturing me. OCD makes it so much worse. It’s been a month already. I need to start letting go but can’t stop. Any advice for letting things go .. ?
