Advice for relationships ocd

My husband told me recently he was going to hang out with a local friend he often goes to see. It got very late and I heard nothing from him. Tried calling and texting. Stayed up all night thinking maybe he was dead or injured. Logged into our cell phone account to see if I could find any recent location and discovered he had talked to someone on the phone that night but he was like 2 hours away from home at that time. And also saw a phone number he was spending hours on the phone with every day. I had been confronting him about his secrecy prior to that and he kept telling me it was this friend or that friend, or he was just taking the dog on a long walk or having a fire out back. He finally called me back in the morning and I yelled at him. He told me he was randomly with two friends from longer ago and had gotten drunk and passed out, and hadn't told me about these plans because I had a heart surgery a few weeks prior and health concerns and he didn't want to stress me out. He told me the phone number was a girl that he related to on trauma factors and that he views like a little sister. He said he didn't tell me because he was caught up in his trauma spilling of events he didn't share with a single person since they occurred to him 35 years ago, due to feelings of shame and anger, and that he thought I would view it as emotional cheating. I told him it really could be viewed as emotional cheating and in principle, honesty shouldn't be dependent upon the outcome... lying isn't justified because I would be upset by the truth. Since then, he's been more open with me and tells me when that girl is calling, talks to me about their conversations, answers her calls when I'm present. I talked to him about boundaries and things I'm uncomfortable with or bothered by and he changes those things. Especially because I have trauma from an emotionally abusive ex, having him lie to me when I directly questioned him about what I was perceiving or experiencing and telling me those experiences weren't real, when they actually WERE real, has really messed me up. Now when he wants to hang out with a friend, I don't trust it. But I'm handling these feelings in destructive OCD ways. I spend literally the entire time he's gone thinking and thinking and thinking about what if he's lying or what he might be doing instead of what he said. I call and text him intermittently and feel like all of my obsessive thoughts are confirmed if he doesn't answer right away. I'm always checking the phone history. The driving toll history. Scrutinizing everything. I cannot get out of this mindset. It's like this horrible mixture of emotional flashbacks and OCD. I don't want to live like this. I want to work on my relationship in productive ways. I want to be able to use my own time while my husband is gone. Even if he lied to me and is somewhere other than he said, I don't want to lie in bed just thinking and thinking and thinking for entire days and nights. I'm not sure what I'm really asking here. This is just the only place where I feel like I can share this without people thinking "wow she's crazy".

Hi all, I’m F(20) and I’ve been in a relationship with my boyfriend M(20) for 10 months now. Lately it feels like I’ve been getting triggered at the tiniest thing. My relationship OCD is centered around the idea that my bf will leave me, that suddenly his feelings will change and he’ll never look back. Inherently I know this is irrational and I know he loves me very much (as he tells me repeatedly when I compulsively ask for reassurance). I just can’t make my brain stop. I just feel so unsecured. He will mention that one of his friends drove an hour to see him for only 30 minutes. I will then spiral that I am not possibly doing enough and it’s because he’s secretly done with me and he’s longing for a reason to leave and go be with this friend instead. See? Truly irrational. But I cannot stop it. Any tips at all? Maybe I’m at least not alone in this. I often feel literally insane:(

I’m struggling a ton rn and would love some insight from people. My bf and I broke up bc my OCD got to the point where it was extremely damaging to my exes mental health. We’ve been on a break for the last 2 months while I get therapy and help and he wants to try again in August. We talk everyday and fall asleep on the phone but I’m miserable anxious about what he’s been doing during the break. My mind is flooded with the idea that he might follow new girls on Instagram or he flirting and talking to new girls. It’s KILLING me. I’ve made up an entire situation w no proof. And I’m scared it’s not my OCD talking but a gut feeling. I know we aren’t together but it’s not fair to emotionally invest in each other if he’s not being loyal like I am. I’m just losing my mind and need help honestly.
